Simplifying 5x + -1(2x2 + -8x) + 5x2 = 0 Reorder the terms: 5x + -1(-8x + 2x2) + 5x2 = 0 5x + (-8x * -1 + 2x2 * -1) + 5x2 = 0 5x + (8x + -2x2) + 5x2 = 0 Combine like terms: 5x + 8x = 13x 13x + -2x2 + 5x2 = 0 Combine like terms: -2x2 + 5x2 = 3x2 13x + 3x2 = 0 Solving 13x + 3x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(13 + 3x) = 0Subproblem 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 = 0Subproblem 2
Set the factor '(13 + 3x)' equal to zero and attempt to solve: Simplifying 13 + 3x = 0 Solving 13 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-13' to each side of the equation. 13 + -13 + 3x = 0 + -13 Combine like terms: 13 + -13 = 0 0 + 3x = 0 + -13 3x = 0 + -13 Combine like terms: 0 + -13 = -13 3x = -13 Divide each side by '3'. x = -4.333333333 Simplifying x = -4.333333333Solution
x = {0, -4.333333333}
