Simplifying 8x2 + -2x + -18 = -18 Reorder the terms: -18 + -2x + 8x2 = -18 Add '18' to each side of the equation. -18 + -2x + 18 + 8x2 = -18 + 18 Reorder the terms: -18 + 18 + -2x + 8x2 = -18 + 18 Combine like terms: -18 + 18 = 0 0 + -2x + 8x2 = -18 + 18 -2x + 8x2 = -18 + 18 Combine like terms: -18 + 18 = 0 -2x + 8x2 = 0 Solving -2x + 8x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2x'. 2x(-1 + 4x) = 0 Ignore the factor 2.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 = 0Subproblem 2
Set the factor '(-1 + 4x)' equal to zero and attempt to solve: Simplifying -1 + 4x = 0 Solving -1 + 4x = 0 Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + 4x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 4x = 0 + 1 4x = 0 + 1 Combine like terms: 0 + 1 = 1 4x = 1 Divide each side by '4'. x = 0.25 Simplifying x = 0.25Solution
x = {0, 0.25}
