What are the values of x in the equation x2 – 6x + 9 = 25? x = –2 or x = 8 x = –1 or x = –11 x = 1 or x = 11 x = 2 or x = –8

x = 8,-2

Step-by-step explanation:

First, complete the square on LHS (Left-Handed Side).

Make sure to recall the perfect square formula. Rewrite another equation with (x-3)² instead.

Square both sides of equation.

Because x² = (-x)² which means that it’s possible for x to be negative. Thus, write plus-minus beside √25 and cancel square of LHS.

Therefore, x = 5+3 or x = -5+3

Thus, x = 8,-2

The method above is called completing the square method.
