Simplifying (4x + -9)(2x + 3) = 0 Reorder the terms: (-9 + 4x)(2x + 3) = 0 Reorder the terms: (-9 + 4x)(3 + 2x) = 0 Multiply (-9 + 4x) * (3 + 2x) (-9(3 + 2x) + 4x * (3 + 2x)) = 0 ((3 * -9 + 2x * -9) + 4x * (3 + 2x)) = 0 ((-27 + -18x) + 4x * (3 + 2x)) = 0 (-27 + -18x + (3 * 4x + 2x * 4x)) = 0 (-27 + -18x + (12x + 8x2)) = 0 Combine like terms: -18x + 12x = -6x (-27 + -6x + 8x2) = 0 Solving -27 + -6x + 8x2 = 0 Solving for variable 'x'. Factor a trinomial. (-3 + -2x)(9 + -4x) = 0Subproblem 1
Set the factor '(-3 + -2x)' equal to zero and attempt to solve: Simplifying -3 + -2x = 0 Solving -3 + -2x = 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 + -2x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -2x = 0 + 3 -2x = 0 + 3 Combine like terms: 0 + 3 = 3 -2x = 3 Divide each side by '-2'. x = -1.5 Simplifying x = -1.5Subproblem 2
Set the factor '(9 + -4x)' equal to zero and attempt to solve: Simplifying 9 + -4x = 0 Solving 9 + -4x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -4x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -4x = 0 + -9 -4x = 0 + -9 Combine like terms: 0 + -9 = -9 -4x = -9 Divide each side by '-4'. x = 2.25 Simplifying x = 2.25Solution
x = {-1.5, 2.25}
