30 pts! solve the following equation. (x - 18)^2 = 1
a. x= 19 and x=17
b. x = -19 and x= -17
c. x=-19 and x= 17
d. x= 19 and x= -17

D - x = 19 x = -17

Step-by-step explanation:

Factor the equation to make the problem easier - you should have this:

(x - 18) (x + 18) = 1

Set each binomial to 1:

x - 18 = 1

x + 18 = 1

This should give you x = 19 and x = -17
