Solution for 3x=(x-6)(x-6) equation: 


Simplifying
3x = (x + -6)(x + -6)

Reorder the terms:
3x = (-6 + x)(x + -6)

Reorder the terms:
3x = (-6 + x)(-6 + x)

Multiply (-6 + x) * (-6 + x)
3x = (-6(-6 + x) + x(-6 + x))
3x = ((-6 * -6 + x * -6) + x(-6 + x))
3x = ((36 + -6x) + x(-6 + x))
3x = (36 + -6x + (-6 * x + x * x))
3x = (36 + -6x + (-6x + x2))

Combine like terms: -6x + -6x = -12x
3x = (36 + -12x + x2)

Solving
3x = 36 + -12x + x2
