Solution for 0=(x+8)(x+8) equation: 


Simplifying
0 = (x + 8)(x + 8)

Reorder the terms:
0 = (8 + x)(x + 8)

Reorder the terms:
0 = (8 + x)(8 + x)

Multiply (8 + x) * (8 + x)
0 = (8(8 + x) + x(8 + x))
0 = ((8 * 8 + x * 8) + x(8 + x))
0 = ((64 + 8x) + x(8 + x))
0 = (64 + 8x + (8 * x + x * x))
0 = (64 + 8x + (8x + x2))

Combine like terms: 8x + 8x = 16x
0 = (64 + 16x + x2)

Solving
0 = 64 + 16x + x2

Solving for variable 'x'.

Combine like terms: 0 + -64 = -64
-64 + -16x + -1x2 = 64 + 16x + x2 + -64 + -16x + -1x2

Reorder the terms:
-64 + -16x + -1x2 = 64 + -64 + 16x + -16x + x2 + -1x2

Combine like terms: 64 + -64 = 0
-64 + -16x + -1x2 = 0 + 16x + -16x + x2 + -1x2
-64 + -16x + -1x2 = 16x + -16x + x2 + -1x2

Combine like terms: 16x + -16x = 0
-64 + -16x + -1x2 = 0 + x2 + -1x2
-64 + -16x + -1x2 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
-64 + -16x + -1x2 = 0

Factor out the Greatest Common Factor (GCF), '-1'.
-1(64 + 16x + x2) = 0

Factor a trinomial.
-1((8 + x)(8 + x)) = 0

Ignore the factor -1.
