3. Solve for x: (x - 9)2 = 1

Answer 1

x-9 = 1 ==>x=10 or x-9 =-1 ==>x=8

Answer 2

\[x-9=\pm1\]\[x = 9 \pm 1\]

Answer 3

(x-9)^2=1
x-9=sqrt1
x-9=1, x-9=-1
x=10, x=8

Answer 4

its completing the square

Answer 5

i got x=9+_ squrt 163 is that right

Answer 6

No, the answers are x = 10 or x = 8

Answer 7

how can u show me plz

Answer 8

Start with (x-9)^2 = 1 and take the square root of both sides to get

x - 9 = +-sqrt(1)

Answer 9

Break up the right side to get two equations


x-9 = 1 or x - 9 = -1


Now solve for x in each equation to get


x = 10 or x = 8
