Solution for 0=-3x(x+100) equation:


Simplifying
0 = -3x(x + 100)

Reorder the terms:
0 = -3x(100 + x)
0 = (100 * -3x + x * -3x)
0 = (-300x + -3x2)

Solving
0 = -300x + -3x2

Solving for variable 'x'.
Remove the zero:
300x + 3x2 = -300x + -3x2 + 300x + 3x2

Reorder the terms:
300x + 3x2 = -300x + 300x + -3x2 + 3x2

Combine like terms: -300x + 300x = 0
300x + 3x2 = 0 + -3x2 + 3x2
300x + 3x2 = -3x2 + 3x2

Combine like terms: -3x2 + 3x2 = 0
300x + 3x2 = 0

Factor out the Greatest Common Factor (GCF), '3x'.
3x(100 + x) = 0

Ignore the factor 3.

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 '(100 + x)' equal to zero and attempt to solve: Simplifying 100 + x = 0 Solving 100 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '-100' to each side of the equation. 100 + -100 + x = 0 + -100 Combine like terms: 100 + -100 = 0 0 + x = 0 + -100 x = 0 + -100 Combine like terms: 0 + -100 = -100 x = -100 Simplifying x = -100

Solution

x = {0, -100}
