Degree of a polynomial - Wikipedia In mathematics, the degree of a polynomial is the highest of the degrees of the polynomial's monomials (individual terms) with non-zero coefficients. The degree of a term is the sum of the exponents of the variables that appear in it, and thus is a non-negative integer.The term order has been used as a synonym of degree but, nowadays, may refer to several other concepts (see order of a Factoring and solving equations - Wellesley College Since (x+A)(x+B) = x2 + (A+B)x + AB , we need two numbers A and B whose sum is 1 and whose product is -6 . Integer possibilities that will give a product of -6 are -6 and 1, 6 and -1, -3 and 2, 3 and -2. The only pair whose sum is 1 is (3 and -2) , so the factorization is. x2 + x - 6 = (x+3)(x-2) . Cumulative Test on Polynomials and Factoring factors of 10 and 7 and 5 and 14. Of those two choices, let’s see which one works. ***I know that the larger integer must be negative, since the sum is -3; therefore, I can eliminate A because the larger integer, 10 is positive. For the same reason, I can eliminate D. Let’s try letter C. We’ll multiply: (x+7)(x-10) = x 2 – 10x + 7x – 70 Desmos | Graphing Calculator
