Solution for =(8+x)(6x-3) equation: 


Simplifying
0 = (8 + x)(6x + -3)

Reorder the terms:
0 = (8 + x)(-3 + 6x)

Multiply (8 + x) * (-3 + 6x)
0 = (8(-3 + 6x) + x(-3 + 6x))
0 = ((-3 * 8 + 6x * 8) + x(-3 + 6x))
0 = ((-24 + 48x) + x(-3 + 6x))
0 = (-24 + 48x + (-3 * x + 6x * x))
0 = (-24 + 48x + (-3x + 6x2))

Combine like terms: 48x + -3x = 45x
0 = (-24 + 45x + 6x2)

Solving
0 = -24 + 45x + 6x2

Solving for variable 'x'.

Combine like terms: 0 + 24 = 24
24 + -45x + -6x2 = -24 + 45x + 6x2 + 24 + -45x + -6x2

Reorder the terms:
24 + -45x + -6x2 = -24 + 24 + 45x + -45x + 6x2 + -6x2

Combine like terms: -24 + 24 = 0
24 + -45x + -6x2 = 0 + 45x + -45x + 6x2 + -6x2
24 + -45x + -6x2 = 45x + -45x + 6x2 + -6x2

Combine like terms: 45x + -45x = 0
24 + -45x + -6x2 = 0 + 6x2 + -6x2
24 + -45x + -6x2 = 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
24 + -45x + -6x2 = 0

Factor out the Greatest Common Factor (GCF), '3'.
3(8 + -15x + -2x2) = 0

Factor a trinomial.
3((1 + -2x)(8 + x)) = 0

Ignore the factor 3.

Subproblem 1
Set the factor '(1 + -2x)' equal to zero and attempt to solve:
