(8x-1)(x+3)=

Solution for (8x-1)(x+3)= equation:

Simplifying
(8x + -1)(x + 3) = 0

Reorder the terms:
(-1 + 8x)(x + 3) = 0

Reorder the terms:
(-1 + 8x)(3 + x) = 0

Multiply (-1 + 8x) * (3 + x)
(-1(3 + x) + 8x * (3 + x)) = 0
((3 * -1 + x * -1) + 8x * (3 + x)) = 0
((-3 + -1x) + 8x * (3 + x)) = 0
(-3 + -1x + (3 * 8x + x * 8x)) = 0
(-3 + -1x + (24x + 8x2)) = 0

Combine like terms: -1x + 24x = 23x
(-3 + 23x + 8x2) = 0

Solving
-3 + 23x + 8x2 = 0

Solving for variable 'x'.
