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

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

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

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

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

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

Combine like terms: -8x + -1x = -9x
(8 + -9x + x2) = 0

Solving
8 + -9x + x2 = 0

Solving for variable 'x'.
