y = (x - 1)(x + 2)(x + 5)
Explanation:
Since a + b + c + d = 0, f(1) = 0. One factor is (x - 1).
After division -->
y=(x−1)(x2+7x+10)
The trinomial in parentheses can be factored
Find 2 numbers knowing sum (7) and product (10). They are 2 and 5.
x 2+7x+10=(x+2) (x+5)
y=(x−1) (x+2) (x+5)
A would be correct!
