Question 1016061: Need the solution set of this equation. Thank you
(X-6)^2 +4 = 36
2
The (x-6)^2 should be over 2.

Answer by ankor@dixie-net.com(22740) (Show Source): You can put this solution on YOUR website!
+4 = 36
subtract 4 from both sides
= 32
multiply both sides by 2
(x-6)^2 = 64
FOIL (x-6)(x-6)
x^2 - 6x - 6x + 36 = 64
combine like terms on the left
x^2 - 12x + 36 - 64 = 0
x^2 - 12x - 28 = 0
Factors to
(x-14)(x+2) = 0
two solutions
x = 14
and
x = -2
:
Check both solutions in the original equation
x = 14
+4 = 36
+4 = 36
+4 = 36
32 + 4 = 36; a good solution
and
x= -2
+4 = 36
+4 = 36
+4 = 36
32 + 4 = 36; also OK
