A quadratic has been factored, as shown below:

f (x) = (x - 6) (x + 5)

What are the zeros of the quadratic?

a

6 and - 5

b

6 and 5

c

-6 and 5

d

-6 and - 5

a

Step-by-step explanation:

Given

f (x) = (x - 6) (x + 5)

To find the zeros, let f (x) = 0, that is

(x - 6) (x + 5) = 0

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 5 = 0 ⇒ x = - 5
