Simplifying x2 + 2x = 15m2 Reorder the terms: 2x + x2 = 15m2 Solving 2x + x2 = 15m2 Solving for variable 'x'. Reorder the terms: -15m2 + 2x + x2 = 15m2 + -15m2 Combine like terms: 15m2 + -15m2 = 0 -15m2 + 2x + x2 = 0 Factor a trinomial. (-5m + -1x)(3m + -1x) = 0Subproblem 1
Set the factor '(-5m + -1x)' equal to zero and attempt to solve: Simplifying -5m + -1x = 0 Solving -5m + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '5m' to each side of the equation. -5m + 5m + -1x = 0 + 5m Combine like terms: -5m + 5m = 0 0 + -1x = 0 + 5m -1x = 0 + 5m Remove the zero: -1x = 5m Divide each side by '-1'. x = -5m Simplifying x = -5mSubproblem 2
Set the factor '(3m + -1x)' equal to zero and attempt to solve: Simplifying 3m + -1x = 0 Solving 3m + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-3m' to each side of the equation. 3m + -3m + -1x = 0 + -3m Combine like terms: 3m + -3m = 0 0 + -1x = 0 + -3m -1x = 0 + -3m Remove the zero: -1x = -3m Divide each side by '-1'. x = 3m Simplifying x = 3mSolution
x = {-5m, 3m}
