(x-8)(8x+1)=0

Solution for (x-8)(8x+1)=0 equation:

Simplifying
(x + -8)(8x + 1) = 0

Reorder the terms:
(-8 + x)(8x + 1) = 0

Reorder the terms:
(-8 + x)(1 + 8x) = 0

Multiply (-8 + x) * (1 + 8x)
(-8(1 + 8x) + x(1 + 8x)) = 0
((1 * -8 + 8x * -8) + x(1 + 8x)) = 0
((-8 + -64x) + x(1 + 8x)) = 0
(-8 + -64x + (1 * x + 8x * x)) = 0
(-8 + -64x + (1x + 8x2)) = 0

Combine like terms: -64x + 1x = -63x
(-8 + -63x + 8x2) = 0

Solving
-8 + -63x + 8x2 = 0
