Simplifying (4 + -2x)(x + -3) = 0 Reorder the terms: (4 + -2x)(-3 + x) = 0 Multiply (4 + -2x) * (-3 + x) (4(-3 + x) + -2x * (-3 + x)) = 0 ((-3 * 4 + x * 4) + -2x * (-3 + x)) = 0 ((-12 + 4x) + -2x * (-3 + x)) = 0 (-12 + 4x + (-3 * -2x + x * -2x)) = 0 (-12 + 4x + (6x + -2x2)) = 0 Combine like terms: 4x + 6x = 10x (-12 + 10x + -2x2) = 0 Solving -12 + 10x + -2x2 = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '2'. 2(-6 + 5x + -1x2) = 0 Factor a trinomial. 2((-3 + x)(2 + -1x)) = 0 Ignore the factor 2.Subproblem 1
Set the factor '(-3 + x)' equal to zero and attempt to solve: Simplifying -3 + x = 0 Solving -3 + x = 0 Move all terms containing x to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + x = 0 + 3 x = 0 + 3 Combine like terms: 0 + 3 = 3 x = 3 Simplifying x = 3Subproblem 2
Set the factor '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 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 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Divide each side by '-1'. x = 2 Simplifying x = 2Solution
x = {3, 2}
