Question

Identify the zeros of f(x) = (x + 1)(x − 8)(5x + 2).

1, 2 over 5, 8
−1, −2 over 5,−8
−1, 2 over 5, −8
−1, −2 over 5,8

Answer 1

The zero's are -1, -2/5, 8

Explanation:

f(x) = (x + 1)(x − 8)(5x + 2)

We can use the zero product property

0 = (x + 1)(x − 8)(5x + 2)

0 = x+1 0 = x-8 0 =5x+2

x=-1 x=8 -2 =5x

x=-1 x=8 -2/5 =x

The zero's are -1, -2/5, 8
