What is the factored form of the polynomial?
1 answer:
Answer:
(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)
