Solve the equation by factoring. z2 − 6z − 27 = 0 a. z = –3 or z = 9 b. z = –3 or z = –9 c. z = 3 or z = 9 d. z = 3 or z = –9

The answer is x= 9 and -3

You must fine 2 number that multiply to equal -27 and add to equal -6

(x-9) (x+3)

Then equal the parts of the binomial to zero

x - 9 = 0

x + 3 = 0

You must get x by its self.

When you do so, you'll have the answer as -3 and 9
