(8x-2)(x+5)=

Solution for (8x-2)(x+5)= equation:

Simplifying
(8x + -2)(x + 5) = 0

Reorder the terms:
(-2 + 8x)(x + 5) = 0

Reorder the terms:
(-2 + 8x)(5 + x) = 0

Multiply (-2 + 8x) * (5 + x)
(-2(5 + x) + 8x * (5 + x)) = 0
((5 * -2 + x * -2) + 8x * (5 + x)) = 0
((-10 + -2x) + 8x * (5 + x)) = 0
(-10 + -2x + (5 * 8x + x * 8x)) = 0
(-10 + -2x + (40x + 8x2)) = 0

Combine like terms: -2x + 40x = 38x

Move all terms containing x to the left, all other terms to the right.

Add '-1' to each side of the equation.
1 + -1 + -4x = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -4x = 0 + -1
-4x = 0 + -1

Combine like terms: 0 + -1 = -1
-4x = -1

Divide each side by '-4'.
x = 0.25

Simplifying
x = 0.25
Solution
x = {-5, 0.25}
