2((4 * -3 + x * -3) + x(4 + x)) = 10x
2((-12 + -3x) + x(4 + x)) = 10x
2(-12 + -3x + (4 * x + x * x)) = 10x
2(-12 + -3x + (4x + x2)) = 10x

Combine like terms: -3x + 4x = 1x
2(-12 + 1x + x2) = 10x
(-12 * 2 + 1x * 2 + x2 * 2) = 10x
(-24 + 2x + 2x2) = 10x

Solving
-24 + 2x + 2x2 = 10x

Solving for variable 'x'.

Subproblem 1

Set the factor '(-2 + -1x)' equal to zero and attempt to solve: Simplifying -2 + -1x = 0 Solving -2 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 2 + -1x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + -1x = 0 + 2 -1x = 0 + 2 Combine like terms: 0 + 2 = 2 -1x = 2 Divide each side by '-1'. x = -2 Simplifying x = -2

Subproblem 2

Set the factor '(6 + -1x)' equal to zero and attempt to solve: Simplifying 6 + -1x = 0 Solving 6 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + -1x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + -1x = 0 + -6 -1x = 0 + -6 Combine like terms: 0 + -6 = -6 -1x = -6 Divide each side by '-1'. x = 6 Simplifying x = 6

Solution

x = {-2, 6}
