Solution for (x-3)(x+3)=(x-3)(x-3) equation: 


Simplifying
(x + -3)(x + 3) = (x + -3)(x + -3)

Reorder the terms:
(-3 + x)(x + 3) = (x + -3)(x + -3)

Reorder the terms:
(-3 + x)(3 + x) = (x + -3)(x + -3)

Multiply (-3 + x) * (3 + x)
(-3(3 + x) + x(3 + x)) = (x + -3)(x + -3)
((3 * -3 + x * -3) + x(3 + x)) = (x + -3)(x + -3)
((-9 + -3x) + x(3 + x)) = (x + -3)(x + -3)
(-9 + -3x + (3 * x + x * x)) = (x + -3)(x + -3)
(-9 + -3x + (3x + x2)) = (x + -3)(x + -3)

Combine like terms: -3x + 3x = 0
(-9 + 0 + x2) = (x + -3)(x + -3)
(-9 + x2) = (x + -3)(x + -3)

Reorder the terms:
-9 + x2 = (-3 + x)(x + -3)

Reorder the terms:
-9 + x2 = (-3 + x)(-3 + x)

Multiply (-3 + x) * (-3 + x)
-9 + x2 = (-3(-3 + x) + x(-3 + x))
-9 + x2 = ((-3 * -3 + x * -3) + x(-3 + x))
-9 + x2 = ((9 + -3x) + x(-3 + x))
-9 + x2 = (9 + -3x + (-3 * x + x * x))
-9 + x2 = (9 + -3x + (-3x + x2))

Combine like terms: -3x + -3x = -6x
-9 + x2 = (9 + -6x + x2)

Add '-1x2' to each side of the equation.
-9 + x2 + -1x2 = 9 + -6x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-9 + 0 = 9 + -6x + x2 + -1x2
-9 = 9 + -6x + x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-9 = 9 + -6x + 0
-9 = 9 + -6x

Solving
-9 = 9 + -6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.
