Solution for 2x=(x-4)(x-4) equation: 


Simplifying
2x = (x + -4)(x + -4)

Reorder the terms:
2x = (-4 + x)(x + -4)

Reorder the terms:
2x = (-4 + x)(-4 + x)

Multiply (-4 + x) * (-4 + x)
2x = (-4(-4 + x) + x(-4 + x))
2x = ((-4 * -4 + x * -4) + x(-4 + x))
2x = ((16 + -4x) + x(-4 + x))
2x = (16 + -4x + (-4 * x + x * x))
2x = (16 + -4x + (-4x + x2))

Combine like terms: -4x + -4x = -8x
2x = (16 + -8x + x2)

Solving
2x = 16 + -8x + x2

Solving for variable 'x'.

Reorder the terms:
-16 + 2x + 8x + -1x2 = 16 + -8x + x2 + -16 + 8x + -1x2

Combine like terms: 2x + 8x = 10x
-16 + 10x + -1x2 = 16 + -8x + x2 + -16 + 8x + -1x2

Reorder the terms:
-16 + 10x + -1x2 = 16 + -16 + -8x + 8x + x2 + -1x2

Combine like terms: 16 + -16 = 0
-16 + 10x + -1x2 = 0 + -8x + 8x + x2 + -1x2
-16 + 10x + -1x2 = -8x + 8x + x2 + -1x2

Combine like terms: -8x + 8x = 0
-16 + 10x + -1x2 = 0 + x2 + -1x2
-16 + 10x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-16 + 10x + -1x2 = 0
