Simplifying
(5x + -1)(2x + 3) = 8x

Reorder the terms:
(-1 + 5x)(2x + 3) = 8x

Reorder the terms:
(-1 + 5x)(3 + 2x) = 8x

Multiply (-1 + 5x) * (3 + 2x)
(-1(3 + 2x) + 5x * (3 + 2x)) = 8x
((3 * -1 + 2x * -1) + 5x * (3 + 2x)) = 8x
((-3 + -2x) + 5x * (3 + 2x)) = 8x
(-3 + -2x + (3 * 5x + 2x * 5x)) = 8x
(-3 + -2x + (15x + 10x2)) = 8x

Combine like terms: -2x + 15x = 13x
(-3 + 13x + 10x2) = 8x

Solving
-3 + 13x + 10x2 = 8x

Solving for variable 'x'.

Reorder the terms:
-3 + 13x + -8x + 10x2 = 8x + -8x

Combine like terms: 13x + -8x = 5x
-3 + 5x + 10x2 = 8x + -8x

Combine like terms: 8x + -8x = 0
-3 + 5x + 10x2 = 0

Begin completing the square.  Divide all terms by
10 the coefficient of the squared term: 

Divide each side by '10'.
-0.3 + 0.5x + x2 = 0.0

Move the constant term to the right:

Add '0.3' to each side of the equation.
-0.3 + 0.5x + 0.3 + x2 = 0.0 + 0.3

Reorder the terms:
-0.3 + 0.3 + 0.5x + x2 = 0.0 + 0.3

Combine like terms: -0.3 + 0.3 = 0.0
0.0 + 0.5x + x2 = 0.0 + 0.3
0.5x + x2 = 0.0 + 0.3

Combine like terms: 0.0 + 0.3 = 0.3
0.5x + x2 = 0.3

The x term is 0.5x.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5x + 0.0625 + x2 = 0.3 + 0.0625

Reorder the terms:
0.0625 + 0.5x + x2 = 0.3 + 0.0625

Combine like terms: 0.3 + 0.0625 = 0.3625
0.0625 + 0.5x + x2 = 0.3625

Factor a perfect square on the left side:
(x + 0.25)(x + 0.25) = 0.3625

Calculate the square root of the right side: 0.602079729
