Simplifying 5x + -1(5x2 + -2x) + 8x2 = 0 Reorder the terms: 5x + -1(-2x + 5x2) + 8x2 = 0 5x + (-2x * -1 + 5x2 * -1) + 8x2 = 0 5x + (2x + -5x2) + 8x2 = 0 Combine like terms: 5x + 2x = 7x 7x + -5x2 + 8x2 = 0 Combine like terms: -5x2 + 8x2 = 3x2 7x + 3x2 = 0 Solving 7x + 3x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(7 + 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 '(7 + 3x)' equal to zero and attempt to solve: Simplifying 7 + 3x = 0 Solving 7 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 3x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 3x = 0 + -7 3x = 0 + -7 Combine like terms: 0 + -7 = -7 3x = -7 Divide each side by '3'. x = -2.333333333 Simplifying x = -2.333333333Solution
x = {0, -2.333333333}
