Factor to find the zeros of the function defined by the quadratic expression. 12x2 − 156x + 480

12(x-5)(x-8)

Step-by-step explanation:

Trinomials are three term algebraic expressions typically featuring variables to exponent powers. To break these trinomials down we factor them using the diamond method or GCF. The diamond method states that for a trinomial multiply a*c then find two numbers which multiply to this number and add to b. When you find those numbers, write them as .

a=1, c=40

ac=40 and add to b=-13 which -5 and -8 satisfy.
