Simplifying 2x2 + 4x = 42x Reorder the terms: 4x + 2x2 = 42x Solving 4x + 2x2 = 42x Solving for variable 'x'. Reorder the terms: 4x + -42x + 2x2 = 42x + -42x Combine like terms: 4x + -42x = -38x -38x + 2x2 = 42x + -42x Combine like terms: 42x + -42x = 0 -38x + 2x2 = 0 Factor out the Greatest Common Factor (GCF), '2x'. 2x(-19 + x) = 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 '(-19 + x)' equal to zero and attempt to solve: Simplifying -19 + x = 0 Solving -19 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '19' to each side of the equation. -19 + 19 + x = 0 + 19 Combine like terms: -19 + 19 = 0 0 + x = 0 + 19 x = 0 + 19 Combine like terms: 0 + 19 = 19 x = 19 Simplifying x = 19Solution
x = {0, 19}
