-1 + 10x = ((-1 + -4x) + 5x * (1 + 4x))
-1 + 10x = (-1 + -4x + (1 * 5x + 4x * 5x))
-1 + 10x = (-1 + -4x + (5x + 20x2))

Combine like terms: -4x + 5x = 1x
-1 + 10x = (-1 + 1x + 20x2)

Add '1' to each side of the equation.
-1 + 1 + 10x = -1 + 1x + 1 + 20x2

Combine like terms: -1 + 1 = 0
0 + 10x = -1 + 1x + 1 + 20x2
10x = -1 + 1x + 1 + 20x2

Reorder the terms:
10x = -1 + 1 + 1x + 20x2

Combine like terms: -1 + 1 = 0
10x = 0 + 1x + 20x2
10x = 1x + 20x2
