Simplifying (2x + 7)(3x + 2) = 0 Reorder the terms: (7 + 2x)(3x + 2) = 0 Reorder the terms: (7 + 2x)(2 + 3x) = 0 Multiply (7 + 2x) * (2 + 3x) (7(2 + 3x) + 2x * (2 + 3x)) = 0 ((2 * 7 + 3x * 7) + 2x * (2 + 3x)) = 0 ((14 + 21x) + 2x * (2 + 3x)) = 0 (14 + 21x + (2 * 2x + 3x * 2x)) = 0 (14 + 21x + (4x + 6x2)) = 0 Combine like terms: 21x + 4x = 25x (14 + 25x + 6x2) = 0 Solving 14 + 25x + 6x2 = 0 Solving for variable 'x'. Factor a trinomial. (7 + 2x)(2 + 3x) = 0Subproblem 1
Set the factor '(7 + 2x)' equal to zero and attempt to solve: Simplifying 7 + 2x = 0 Solving 7 + 2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 2x = 0 + -7 2x = 0 + -7 Combine like terms: 0 + -7 = -7 2x = -7 Divide each side by '2'. x = -3.5 Simplifying x = -3.5Subproblem 2
Set the factor '(2 + 3x)' equal to zero and attempt to solve: Simplifying 2 + 3x = 0 Solving 2 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + 3x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + 3x = 0 + -2 3x = 0 + -2 Combine like terms: 0 + -2 = -2 3x = -2 Divide each side by '3'. x = -0.6666666667 Simplifying x = -0.6666666667Solution
x = {-3.5, -0.6666666667}
