What is the factored form of the polynomial? x2 + 9x +20 i (x - 4)(x - 5) (x - 2)(x - 10) (x + 4)(x + 5) (x + 2)(x + 10) mark this and return save and exit

(x + 4)(x + 5)

Step-by-step explanation:

Given

x² + 9x + 20

Consider the factors of the constant term (+ 20) which sum to give the coefficient of the x- term (+ 9)

The factors are + 4 and + 5, since

4 × 5 = 20 and 5 + 4 = 9, hence

x² + 9x + 20 = (x + 4)(x + 5)
