In one sentence, describe what the following article is about: . Not only does smoking cause cancer and many other health problems, it may also be the cause of your heartburn. Smoking has been linked with heartburn and gastroesophageal reflux disease (GERD). Studies have found that smoking weakens the lower esophageal sphincter, which is the muscle that keeps your stomach contents from backing up into your esophagus. A weakened lower esophageal sphincter is more likely to allow stomach acids to escape and cause damage to your esophagus. Talk to your doctor about smoking cessation programs in your area, if you want to quit smoking. Try using the START acronym to quit smoking:   S= Set a quit date. T= Tell friends and family. A= Anticipate challenges ahead. R= Remove tobacco products for home, work, and car. T= Talk to your doctor for more support. . Being overweight is thought to be a contributor to heartburn because the excess fat on your abdomen puts pressure on your stomach and may force your stomach contents back up into your esophagus. Studies have shown that a drastic weight loss is not necessary to help relieve heartburn caused by being overweight. Even a small weight loss, 5 to 10% of your body weight, may help relieve your heartburn. To lose weight, try to limit calories to 1800 to 2000 kcal a day, while also exercising for 30 minutes five times per week.  You can use a fitness tracker or application to log your food and keep track of your activity. Tight pants and belts may be contributing to your heartburn by causing too much pressure on your abdomen and causing your stomach contents to back up. Make sure that your pants fit comfortably and that you do not wear your belt too tight. Choose clothing that is a size too big or that has an elastic waistband if your heartburn is severe. If you often suffer from nighttime heartburn, there are two positions that seem to be the most effective against heartburn: sleeping on your left side and sleeping with your upper body elevated. Try one or both of these sleep positions to see if either one helps to relieve your heartburn.  Sleeping on your left side helps aid digestion. Try sleeping on your left side if elevating your upper body does not seem to help. Sleeping with your upper body elevated reduces the possibility that stomach acid will flow up your esophagus. Try using a wedge-shaped pillow to elevate your whole upper body. Using regular pillows will just elevate your head. Stress may contribute to your heartburn symptoms by causing your stomach to produce more stomach acid. Incorporating relaxation techniques into your daily routine, especially after you eat, may help to relieve heartburn. Try meditation, yoga, massage, aromatherapy, deep breathing, or something else to help yourself relax every day.
Summary: Quit smoking Lose weight Wear loose fitting clothing. Change your usual sleeping position. Relax every day.

In one sentence, describe what the following article is about: . You might have already learned the FOIL method, or "First, Outside, Inside, Last," to multiply expressions like (x+2)(x+4). It's useful to know how this strategy works before we get to factoring:  Multiply the First terms: (x+2)(x+4) = x2 + __ Multiply the Outside terms: (x+2)(x+4) = x2+4x + __ Multiply the Inside terms: (x+2)(x+4) = x2+4x+2x + __ Multiply the Last terms: (x+2)(x+4) = x2+4x+2x+8  Simplify: x2+4x+2x+8 = x2+6x+8 When you multiply two binomials together in the FOIL method, you end up with a trinomial (an expression with three terms) in the form ax2+bx+c, where a, b, and c are ordinary numbers. If you start with an equation in the same form, you can factor it back into two binomials.  If the equation isn't written in this order, move the terms around so they are. For example, rewrite 3x - 10 + x2 as x2 + 3x - 10. Because the highest exponent is 2 (x2, this type of expression is "quadratic." For now, just write (__   __)(__   __) in the space where you'll write the answer. We'll fill this out as we go. Don't write + or - between the blank terms yet, since we don't know which it will be. For simple problems, where the first term of your trinomial is just x2, the terms in the First position will always be x and x. These are the factors of the term x2, since x times x = x2.  Our example x2 + 3x - 10 just begins with x2, so we can write: (x   __)(x   __) We'll cover more complicated problems in the next section, including trinomials that begin with a term like 6x2 or -x2. For now, follow the example problem. If you go back and reread the FOIL method step, you'll see that multiplying the Last terms together gives you the final term in the polynomial (the one with no x). So to factor, we need to find two numbers that multiply to form the last term.  In our example x2 + 3x - 10, the last term is -10. What are the factors of -10? What two numbers multiplied together equal -10? There are a few possibilities: -1 times 10, 1 times -10, -2 times 5, or 2 times -5. Write these pairs down somewhere to remember them. Don't change our answer yet. It still looks like this: (x  __)(x   __). We've narrowed the Last terms down to a few possibilities. Use trial and error to test each possibility, multiplying the Outside and Inside terms, and comparing the result to our trinomial. For example:  Our original problem has an "x" term of 3x, so that's what we want to end up with in this test. Test -1 and 10: (x-1)(x+10). The Outside + Inside = 10x - x = 9x. Nope. Test 1 and -10: (x+1)(x-10). -10x + x = -9x. That's not right. In fact, once you test -1 and 10, you know that 1 and -10 will just be the opposite of the answer above: -9x instead of 9x. Test -2 and 5: (x-2)(x+5). 5x - 2x = 3x. That matches the original polynomial, so this is the correct answer: (x-2)(x+5). In simple cases like this, when you don't have a constant in front of the x2 term, you can use a shortcut: just add the two factors together and put an "x" after it (-2+5 → 3x). This won't work for more complicated problems, though, so it's good to remember the "long way" described above.
Summary: Learn FOIL multiplication Understand factoring. Write a space for the answer in FOIL form. Fill out the First terms. Use factoring to guess at the Last terms. Test which possibilities work with Outside and Inside multiplication.
