Simplifying (5x + -1)(3x + 4) = 0 Reorder the terms: (-1 + 5x)(3x + 4) = 0 Reorder the terms: (-1 + 5x)(4 + 3x) = 0 Multiply (-1 + 5x) * (4 + 3x) (-1(4 + 3x) + 5x * (4 + 3x)) = 0 ((4 * -1 + 3x * -1) + 5x * (4 + 3x)) = 0 ((-4 + -3x) + 5x * (4 + 3x)) = 0 (-4 + -3x + (4 * 5x + 3x * 5x)) = 0 (-4 + -3x + (20x + 15x2)) = 0 Combine like terms: -3x + 20x = 17x (-4 + 17x + 15x2) = 0 Solving -4 + 17x + 15x2 = 0 Solving for variable 'x'. Factor a trinomial. (-4 + -3x)(1 + -5x) = 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 + -5x)' equal to zero and attempt to solve: Simplifying 1 + -5x = 0 Solving 1 + -5x = 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 + -5x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -5x = 0 + -1 -5x = 0 + -1 Combine like terms: 0 + -1 = -1 -5x = -1 Divide each side by '-5'. x = 0.2 Simplifying x = 0.2Solution
x = {-1.333333333, 0.2}
