WebSince you are adding the polynomials you have 4x^2 + 3x - 5 + 2x^2 - x + 1. To add them you do exactly as the instructions say, combine like terms. This just means look for matching variables. ... I will give a different example to further help. x^4 - 7x^3 + 3 - 5x^4 + 8x^3 + … WebTo multiply to polynomials, we just multiply every term of one polynomial with every term of the other polynomial and then add all the results. Here is an example to multiply polynomials. For example, (2x + 3y)(4x - 5y) = 2x(4x - 5y) + 3y(4x - 5y) = 8x 2 - 10xy + 12xy - 15y 2. ⇒ 8x 2 + 2xy - 15y 2. Division of Polynomials

We can add and subtract polynomials by combining like terms, which are terms that contain the same variables raised to the same exponents. For example, 5 x 2 5 x 2 and −2 x 2 −2 x 2 are like terms, and can be added to get 3 x 2, 3 x 2, but 3 x 3 x and 3 x 2 3 x 2 are not like terms, and therefore cannot ... dr dray tretinoin routine
