Question

X^2+3x-18 what are the zeros of r(x)?

Answer 1

Explanation:

18 has factors of 9 and 2 or 6 and 3

Those factors must differ by 3, so 6 and 3 in some order is your answer.

(x + 6) (x - 3) = r(x)

You have to make x a value that turns the factor into 0.

x + 6 = 0

x = - 6

x - 3 = 0

x = 3

So the zeros are (3,0) and (- 6,0)
