X^2-12=-11
First add 11: x^2-12+11=0
Next: (x-11)(x-1)=0
Set each equal to 0: (x-11)=0 (x-1)=0
Get x alone by adding: x=11 x=1
Answer: (11,1)
Check work by plugging numbers into original equation.

x^2-12x=-11
(x-6)^2 -36=-11
(x-6)^2 = 36-11
(x-6)^2 =25
x-6 =+/-5
x = 6 +5 =11
x = 6 -5 =1
x^2-12x=-11
(x-6)^2 -36=-11
(x-6)^2 = 36-11
(x-6)^2 =25
