Simplifying 10 = 2x(2x + -3) Reorder the terms: 10 = 2x(-3 + 2x) 10 = (-3 * 2x + 2x * 2x) 10 = (-6x + 4x2) Solving 10 = -6x + 4x2 Solving for variable 'x'. Reorder the terms: 10 + 6x + -4x2 = -6x + 6x + 4x2 + -4x2 Combine like terms: -6x + 6x = 0 10 + 6x + -4x2 = 0 + 4x2 + -4x2 10 + 6x + -4x2 = 4x2 + -4x2 Combine like terms: 4x2 + -4x2 = 0 10 + 6x + -4x2 = 0 Factor out the Greatest Common Factor (GCF), '2'. 2(5 + 3x + -2x2) = 0 Factor a trinomial. 2((5 + -2x)(1 + x)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(5 + -2x)' equal to zero and attempt to solve: Simplifying 5 + -2x = 0 Solving 5 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -2x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -2x = 0 + -5 -2x = 0 + -5 Combine like terms: 0 + -5 = -5 -2x = -5 Divide each side by '-2'. x = 2.5 Simplifying x = 2.5Subproblem 2
Set the factor '(1 + x)' equal to zero and attempt to solve: Simplifying 1 + x = 0 Solving 1 + x = 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 + x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + x = 0 + -1 x = 0 + -1 Combine like terms: 0 + -1 = -1 x = -1 Simplifying x = -1Solution
x = {2.5, -1}
