Solution for 256=x^2(x+8)(x+8) equation: 


Simplifying
256 = x2(x + 8)(x + 8)

Reorder the terms:
256 = x2(8 + x)(x + 8)

Reorder the terms:
256 = x2(8 + x)(8 + x)

Multiply (8 + x) * (8 + x)
256 = x2(8(8 + x) + x(8 + x))
256 = x2((8 * 8 + x * 8) + x(8 + x))
256 = x2((64 + 8x) + x(8 + x))
256 = x2(64 + 8x + (8 * x + x * x))
256 = x2(64 + 8x + (8x + x2))

Combine like terms: 8x + 8x = 16x
256 = x2(64 + 16x + x2)
256 = (64 * x2 + 16x * x2 + x2 * x2)
256 = (64x2 + 16x3 + x4)

Solving
256 = 64x2 + 16x3 + x4

Solving for variable 'x'.

Reorder the terms:
256 + -64x2 + -16x3 + -1x4 = 64x2 + -64x2 + 16x3 + -16x3 + x4 + -1x4
