Question

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

Answer 1

is that :\[\left( x-9 \right)^{2}=1\]

Answer 2

x-9 is either equal to -1 or 1.
write two equations, and solve both.

Answer 3

Yes Pax

Answer 4

cathy is right... reversing the squares on both sides you would get: \[x-9=\pm1\]\[x=\pm1+9\]
So, \[x= 1+ 9 = 10\] or \[x= -1+ 9 = 8\]
x= 8,10
