Simplifying (2x + 3)(5x + 1) = 0 Reorder the terms: (3 + 2x)(5x + 1) = 0 Reorder the terms: (3 + 2x)(1 + 5x) = 0 Multiply (3 + 2x) * (1 + 5x) (3(1 + 5x) + 2x * (1 + 5x)) = 0 ((1 * 3 + 5x * 3) + 2x * (1 + 5x)) = 0 ((3 + 15x) + 2x * (1 + 5x)) = 0 (3 + 15x + (1 * 2x + 5x * 2x)) = 0 (3 + 15x + (2x + 10x2)) = 0 Combine like terms: 15x + 2x = 17x (3 + 17x + 10x2) = 0 Solving 3 + 17x + 10x2 = 0 Solving for variable 'x'. Factor a trinomial. (3 + 2x)(1 + 5x) = 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 '(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 = {-1.5, -0.2}
