Simplifying 4x + 2x2 + -1(2x + -3x2) = 0 4x + 2x2 + (2x * -1 + -3x2 * -1) = 0 4x + 2x2 + (-2x + 3x2) = 0 Reorder the terms: 4x + -2x + 2x2 + 3x2 = 0 Combine like terms: 4x + -2x = 2x 2x + 2x2 + 3x2 = 0 Combine like terms: 2x2 + 3x2 = 5x2 2x + 5x2 = 0 Solving 2x + 5x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), 'x'. x(2 + 5x) = 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 '(2 + 5x)' equal to zero and attempt to solve: Simplifying 2 + 5x = 0 Solving 2 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 5x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 5x = 0 + -2 5x = 0 + -2 Combine like terms: 0 + -2 = -2 5x = -2 Divide each side by '5'. x = -0.4 Simplifying x = -0.4Solution
x = {0, -0.4}
