Answer:
x = 3 twice
Step-by-step explanation:
x^2 = 6x - 9
Rewrite by subtracting 6x from both sides and add 9 to both sides.
x² - 6x + 9 = 0
Factorise by finding factor of +9 that add up to -6
These factors are -3 and -3 that is
-3 -3 = -6 and -3×-3 = 9
Rewrite equation
x² - 3x - 3x + 9 = 0
x ( x-3) -3(x -3) = 0
Therefore
(x -3)(x-3) = 0
x - 3 = 0 or x - 3 = 0
x = 3 or x = 3
x = 3 twice
