Question

Solve for x: (x - 9)2 =1
Completing the square.

Answer 1

No need to complete the square for this one.

Answer 2

(x - 9)^2 =1
x - 9 = ±sqrt(1)
x = ±sqrt(1) + 9

Answer 3

already its complete square form
hence (x-9)^2=1
or (x-9)^ -1=0
or (x-9-1)(x-9+1)=0
(x-10)(x-8)=0
or x-10=0 or x-8=0
hence x=10,8

Answer 4

x=5

Answer 5

(x - 9)^2 =1
x - 9 = ±sqrt(1)
x = ±sqrt(1) + 9
x = -1 + 9 = 8
x = 1 + 9 = 10

Answer 6

x=10, 8 oops
