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

Reorder the terms:
2x(-4 + 5x) = x(3x + 6)
(-4 * 2x + 5x * 2x) = x(3x + 6)
(-8x + 10x2) = x(3x + 6)

Reorder the terms:
-8x + 10x2 = x(6 + 3x)
-8x + 10x2 = (6 * x + 3x * x)
-8x + 10x2 = (6x + 3x2)

Solving
-8x + 10x2 = 6x + 3x2

Solving for variable 'x'.

Reorder the terms:
-8x + -6x + 10x2 + -3x2 = 6x + 3x2 + -6x + -3x2

Combine like terms: -8x + -6x = -14x
-14x + 10x2 + -3x2 = 6x + 3x2 + -6x + -3x2

Combine like terms: 10x2 + -3x2 = 7x2
-14x + 7x2 = 6x + 3x2 + -6x + -3x2

Reorder the terms:
-14x + 7x2 = 6x + -6x + 3x2 + -3x2

Combine like terms: 6x + -6x = 0
-14x + 7x2 = 0 + 3x2 + -3x2
-14x + 7x2 = 3x2 + -3x2

Combine like terms: 3x2 + -3x2 = 0
-14x + 7x2 = 0

Factor out the Greatest Common Factor (GCF), '7x'.
7x(-2 + x) = 0

Ignore the factor 7.

Subproblem 1

Set the factor 'x' equal to zero and attempt to solve: Simplifying x = 0 Solving x = 0 Move all terms containing x to the left, all other terms to the right. Simplifying x = 0

Subproblem 2
