Multiplying PolynomialsDate: 2/10/96 at 20:57:52 From: Anonymous Subject: algebra How do you multiply polynomials? Date: 2/13/96 at 21:35:8 From: Doctor Ethan Subject: Re: algebra To multiply two polynomials, simply multiply each element of the first by each element of the second. The coefficients (the numbers before the variables) multiply, and the exponents add. For example: (2x^3 + x^2 +1)(x + 3) = (2x^3)(x) + (2x^3)(3) + (x^2)(x) + (x^2)(3) + (1)(x) + (1)(3) = 2x^4 + 6x^3 + x^3 + 3x^2 + x + 3 = It is usually good to group all the terms with the same exponent together. 2x^4 + 7x^3 + 3x^2 + x + 3 That was a bit of a fast crash course in polynomials, so you may want to look in a good high school algebra textbook or see a math teacher near you. Good luck! -Doctor Ethan, The Math Forum |
