Solution for (x-2)(x+8)=8(x+1) equation:


Simplifying
(x + -2)(x + 8) = 8(x + 1)

Reorder the terms:
(-2 + x)(x + 8) = 8(x + 1)

Reorder the terms:
(-2 + x)(8 + x) = 8(x + 1)

Multiply (-2 + x) * (8 + x)
(-2(8 + x) + x(8 + x)) = 8(x + 1)
((8 * -2 + x * -2) + x(8 + x)) = 8(x + 1)
((-16 + -2x) + x(8 + x)) = 8(x + 1)
(-16 + -2x + (8 * x + x * x)) = 8(x + 1)
(-16 + -2x + (8x + x2)) = 8(x + 1)

Combine like terms: -2x + 8x = 6x
(-16 + 6x + x2) = 8(x + 1)

Reorder the terms:
-16 + 6x + x2 = 8(1 + x)
-16 + 6x + x2 = (1 * 8 + x * 8)
-16 + 6x + x2 = (8 + 8x)

Solving
-16 + 6x + x2 = 8 + 8x

Solving for variable 'x'.

Reorder the terms:
-16 + -8 + 6x + -8x + x2 = 8 + 8x + -8 + -8x

Combine like terms: -16 + -8 = -24
-24 + 6x + -8x + x2 = 8 + 8x + -8 + -8x

Combine like terms: 6x + -8x = -2x
-24 + -2x + x2 = 8 + 8x + -8 + -8x
