(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 = 7x
(-8 + 7x + x2) = 0

Solving
-8 + 7x + x2 = 0

Solving for variable 'x'.
