Simplifying 3(3x + -3) = (3x + 5)(x + -1) Reorder the terms: 3(-3 + 3x) = (3x + 5)(x + -1) (-3 * 3 + 3x * 3) = (3x + 5)(x + -1) (-9 + 9x) = (3x + 5)(x + -1) Reorder the terms: -9 + 9x = (5 + 3x)(x + -1) Reorder the terms: -9 + 9x = (5 + 3x)(-1 + x) Multiply (5 + 3x) * (-1 + x) -9 + 9x = (5(-1 + x) + 3x * (-1 + x)) -9 + 9x = ((-1 * 5 + x * 5) + 3x * (-1 + x)) -9 + 9x = ((-5 + 5x) + 3x * (-1 + x)) -9 + 9x = (-5 + 5x + (-1 * 3x + x * 3x)) -9 + 9x = (-5 + 5x + (-3x + 3x2)) Combine like terms: 5x + -3x = 2x -9 + 9x = (-5 + 2x + 3x2) Solving -9 + 9x = -5 + 2x + 3x2 Solving for variable 'x'. Reorder the terms: -9 + 5 + 9x + -2x + -3x2 = -5 + 2x + 3x2 + 5 + -2x + -3x2 Combine like terms: -9 + 5 = -4 -4 + 9x + -2x + -3x2 = -5 + 2x + 3x2 + 5 + -2x + -3x2 Combine like terms: 9x + -2x = 7x -4 + 7x + -3x2 = -5 + 2x + 3x2 + 5 + -2x + -3x2 Reorder the terms: -4 + 7x + -3x2 = -5 + 5 + 2x + -2x + 3x2 + -3x2 Combine like terms: -5 + 5 = 0 -4 + 7x + -3x2 = 0 + 2x + -2x + 3x2 + -3x2 -4 + 7x + -3x2 = 2x + -2x + 3x2 + -3x2 Combine like terms: 2x + -2x = 0 -4 + 7x + -3x2 = 0 + 3x2 + -3x2 -4 + 7x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 -4 + 7x + -3x2 = 0 Factor a trinomial. (-4 + 3x)(1 + -1x) = 0Subproblem 1
Set the factor '(-4 + 3x)' equal to zero and attempt to solve: Simplifying -4 + 3x = 0 Solving -4 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '4' to each side of the equation. -4 + 4 + 3x = 0 + 4 Combine like terms: -4 + 4 = 0 0 + 3x = 0 + 4 3x = 0 + 4 Combine like terms: 0 + 4 = 4 3x = 4 Divide each side by '3'. x = 1.333333333 Simplifying x = 1.333333333Subproblem 2
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 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 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1Solution
x = {1.333333333, 1}
