-3x + -6x + 2x2 + 4x2 = (6x + 5)(x + -4)

Combine like terms: -3x + -6x = -9x
-9x + 2x2 + 4x2 = (6x + 5)(x + -4)

Combine like terms: 2x2 + 4x2 = 6x2
-9x + 6x2 = (6x + 5)(x + -4)

Reorder the terms:
-9x + 6x2 = (5 + 6x)(x + -4)

Reorder the terms:
-9x + 6x2 = (5 + 6x)(-4 + x)

Multiply (5 + 6x) * (-4 + x)
-9x + 6x2 = (5(-4 + x) + 6x * (-4 + x))
-9x + 6x2 = ((-4 * 5 + x * 5) + 6x * (-4 + x))
-9x + 6x2 = ((-20 + 5x) + 6x * (-4 + x))
-9x + 6x2 = (-20 + 5x + (-4 * 6x + x * 6x))
-9x + 6x2 = (-20 + 5x + (-24x + 6x2))

Combine like terms: 5x + -24x = -19x
-9x + 6x2 = (-20 + -19x + 6x2)

Add '-6x2' to each side of the equation.
-9x + 6x2 + -6x2 = -20 + -19x + 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
-9x + 0 = -20 + -19x + 6x2 + -6x2
-9x = -20 + -19x + 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
-9x = -20 + -19x + 0
-9x = -20 + -19x

Solving
-9x = -20 + -19x

Solving for variable 'x'.
