5x(x + -7) = 2x(3x + 3)

Reorder the terms:
5x(-7 + x) = 2x(3x + 3)
(-7 * 5x + x * 5x) = 2x(3x + 3)
(-35x + 5x2) = 2x(3x + 3)

Reorder the terms:
-35x + 5x2 = 2x(3 + 3x)
-35x + 5x2 = (3 * 2x + 3x * 2x)
-35x + 5x2 = (6x + 6x2)

Solving
-35x + 5x2 = 6x + 6x2

Solving for variable 'x'.

Reorder the terms:
-35x + -6x + 5x2 + -6x2 = 6x + 6x2 + -6x + -6x2

Combine like terms: -35x + -6x = -41x
-41x + 5x2 + -6x2 = 6x + 6x2 + -6x + -6x2

Combine like terms: 5x2 + -6x2 = -1x2
-41x + -1x2 = 6x + 6x2 + -6x + -6x2

Reorder the terms:
-41x + -1x2 = 6x + -6x + 6x2 + -6x2

Combine like terms: 6x + -6x = 0
-41x + -1x2 = 0 + 6x2 + -6x2
-41x + -1x2 = 6x2 + -6x2

Combine like terms: 6x2 + -6x2 = 0
-41x + -1x2 = 0

Factor out the Greatest Common Factor (GCF), '-1x'.
-1x(41 + x) = 0

Ignore the factor -1.

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

Set the factor '(41 + x)' equal to zero and attempt to solve: Simplifying 41 + x = 0 Solving 41 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-41' to each side of the equation. 41 + -41 + x = 0 + -41 Combine like terms: 41 + -41 = 0 0 + x = 0 + -41 x = 0 + -41 Combine like terms: 0 + -41 = -41 x = -41 Simplifying x = -41

Solution

x = {0, -41}
