To make factoring trinomials easier, write down all of the factors of c that you can think of. In this case, c=20, so: 20 x 1 = 20. 10 x 2 = 20. 5 x 4 = 20. Remember that the two numbers have to multiply to c AND add to b. The only factors of 20 that meet both of these requirements are 4 and 5.

In algebra, a cubic polynomial is an expression made up of four terms that is of the form: . ax³ + bx² + cx + d . Where a, b, c, and d are constants, and x is a variable. Polynomials in this form are called cubic because the highest power of x in the function is 3 (or x cubed).. Unlike factoring trinomials, learning how to factorize a cubic polynomial can be particularly tricky because using ...
