A problem involving a monomial and a three-term polynomial will involve one polynomial that only has a single term. The second polynomial will have three terms, which will be separated by either a plus sign or a minus sign. A polynomial problem involving a monomial and a three-term polynomial will look something like: (ay) * (bx^2 + cx + dy) Example: (2y)(3x^2 + 4x + 5y) Rewrite the problem so that all the terms are separate by distributing the single-term polynomial to both terms in the three-term polynomial. Rewritten, the new equation should look similar to: (ay)(bx^2) + (ay)(cx) + (ay)(dy) Example: (2y)(3x^2 + 4x + 5y) = (2y)(3x^2) + (2y)(4x) + (2y)(5y) The constants refer to the numerical digits in the problem. These are multiplied as they usually would be according to the standard times table. Again, for this step you are multiplying a, b, c, and d together. Example: (2y)(3x^2) + (2y)(4x) + (2y)(5y) = 6(y)(x^2) + 8(y)(x) + 10(y)(y) The variables refer to the letters in the equation. When you multiply these variables, different variables will simply be combined together. When you multiply a variable by a like variable, though, you raise the power of the variable. So multiply the the x and y portions of the equation. Example: 6(y)(x^2) + 8(y)(x) + 10(y)(y) = 6yx^2 + 8xy + 10y^2 Due to the single-term monomial at the beginning of this equation, you don't need to combine like terms. When finished, the final answer should be: abyx^2 + acxy + ady^2 Example substituting sample values for constants: 6yx^2 + 8xy + 10y^2

Summary: Examine the problem. Distribute the monomial to all three terms in the polynomial. Multiply the constants. Multiply the variables. Write your final answer.

When you are first injured, ice can help tame your inflammation. Apply ice packs, frozen vegetables, or a frozen towel to your back during the first 24-72 hours of your injury. After that, switch to heat. Apply cold for 20 minutes at a time. Don't apply cold therapy more than 10 times in a 24 hour period. Put a cloth between your skin and the ice. After the initial period of icing your injury, apply heat. Heat will stimulate blood flow and promote healing. Make a warm compress or buy one. Electric heating pads, hot water bottles, heated gel packs, and saunas can all help. Dry or moist heat may be applied. Try 15-20 minute sessions for minor injuries, and up to two hours at a time for more serious pain. You might try taking the recommended doses of any kind of nonprescription nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen sodium. If these are ineffective at relieving pain, see your doctor for a prescription medication. If you take other medications and are concerned about interaction, see your doctor before you start taking nonprescription medications. . Once your pain has subsided, try some simple stretches at home. Not all stretches work for all kinds of back pain, so only do stretches that feel like they are relaxing your muscles and relieving your pain. Try lying on your back on the floor. Slowly bring one knee up to your chest. Hold it for a count, then slowly extend your leg back to the floor. If your back hurts when you bend it forward, try stretching in the other direction. Lie on your stomach and prop yourself up on your elbows. If that feels fine, place your palms on the floor and extend your elbows slowly so that you are pushing yourself up from the floor. Keep your pelvis on the floor. If a stretch is painful, cease to do it until you have consulted with your doctor. Seek the advice of a chiropractor or your primary care physician to learn about the proper stretching techniques. While you may need to spend some time lying on the floor, rest is not generally a recommended cure for back pain. Rather, continue your ordinary routine as much as you can. Stop any activity that is too painful. Try going for walks, stretching, and otherwise moving around. When you need to rest, try lying on your back on the floor. Prop your knees up with pillows for more comfort. If your back pain does not resolve within a few days, visit your doctor. Back injury that results from a fall or other physical trauma require x-rays and other medical attention. If the pain is severe and unaffected by rest, contact your doctor sooner. Seek immediate care if your pain is accompanied by numbness or tingling.

Summary: Ice your back as soon as you feel the pain. Apply heat going forward. Take over-the-counter anti-inflammatory drugs. Stretch Engage in light activities. Visit a doctor if the pain is severe or long lasting.
