Simplifying (4x + 1)(5x + 6) = 0 Reorder the terms: (1 + 4x)(5x + 6) = 0 Reorder the terms: (1 + 4x)(6 + 5x) = 0 Multiply (1 + 4x) * (6 + 5x) (1(6 + 5x) + 4x * (6 + 5x)) = 0 ((6 * 1 + 5x * 1) + 4x * (6 + 5x)) = 0 ((6 + 5x) + 4x * (6 + 5x)) = 0 (6 + 5x + (6 * 4x + 5x * 4x)) = 0 (6 + 5x + (24x + 20x2)) = 0 Combine like terms: 5x + 24x = 29x (6 + 29x + 20x2) = 0 Solving 6 + 29x + 20x2 = 0 Solving for variable 'x'. Factor a trinomial. (6 + 5x)(1 + 4x) = 0Subproblem 1
Set the factor '(6 + 5x)' equal to zero and attempt to solve: Simplifying 6 + 5x = 0 Solving 6 + 5x = 0 Move all terms containing x to the left, all other terms to the right. Add '-6' to each side of the equation. 6 + -6 + 5x = 0 + -6 Combine like terms: 6 + -6 = 0 0 + 5x = 0 + -6 5x = 0 + -6 Combine like terms: 0 + -6 = -6 5x = -6 Divide each side by '5'. x = -1.2 Simplifying x = -1.2Subproblem 2
Set the factor '(1 + 4x)' equal to zero and attempt to solve: Simplifying 1 + 4x = 0 Solving 1 + 4x = 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 + 4x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 4x = 0 + -1 4x = 0 + -1 Combine like terms: 0 + -1 = -1 4x = -1 Divide each side by '4'. x = -0.25 Simplifying x = -0.25Solution
x = {-1.2, -0.25}
