Solution for =5x(3+2x) equation:


Simplifying
0 = 5x(3 + 2x)
0 = (3 * 5x + 2x * 5x)
0 = (15x + 10x2)

Solving
0 = 15x + 10x2

Solving for variable 'x'.
Remove the zero:
-15x + -10x2 = 15x + 10x2 + -15x + -10x2

Reorder the terms:
-15x + -10x2 = 15x + -15x + 10x2 + -10x2

Combine like terms: 15x + -15x = 0
-15x + -10x2 = 0 + 10x2 + -10x2
-15x + -10x2 = 10x2 + -10x2

Combine like terms: 10x2 + -10x2 = 0
-15x + -10x2 = 0

Factor out the Greatest Common Factor (GCF), '-5x'.
-5x(3 + 2x) = 0

Ignore the factor -5.

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 '(3 + 2x)' equal to zero and attempt to solve: Simplifying 3 + 2x = 0 Solving 3 + 2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + 2x = 0 + -3 Combine like terms: 3 + -3 = 0 0 + 2x = 0 + -3 2x = 0 + -3 Combine like terms: 0 + -3 = -3 2x = -3 Divide each side by '2'. x = -1.5 Simplifying x = -1.5

Solution

x = {0, -1.5}
