Question

What are the zeros of f(x) = x2 + x - 30?

O A. x= -15 and x = 2
O B. x=-6 and x = 5
O C. x= -2 and x = 15
O D. x= -5 and x = 6
SUE

Answer 1

answer B

Explanation:

you need to factor, the factor that works is (x+6)(x-5) then you put in the x values that would make the equation 0, when x is 5 (x-5) = 0 and when x is -6 (x+6) =0
