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


Simplifying
0 = (-3 + x)(-3 + x)

Multiply (-3 + x) * (-3 + x)
0 = (-3(-3 + x) + x(-3 + x))
0 = ((-3 * -3 + x * -3) + x(-3 + x))
0 = ((9 + -3x) + x(-3 + x))
0 = (9 + -3x + (-3 * x + x * x))
0 = (9 + -3x + (-3x + x2))

Combine like terms: -3x + -3x = -6x
0 = (9 + -6x + x2)

Solving
0 = 9 + -6x + x2

Solving for variable 'x'.

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

Reorder the terms:
-9 + 6x + -1x2 = 9 + -9 + -6x + 6x + x2 + -1x2

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

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

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