Simplifying (6x + 7)(2x + -1) = 0 Reorder the terms: (7 + 6x)(2x + -1) = 0 Reorder the terms: (7 + 6x)(-1 + 2x) = 0 Multiply (7 + 6x) * (-1 + 2x) (7(-1 + 2x) + 6x * (-1 + 2x)) = 0 ((-1 * 7 + 2x * 7) + 6x * (-1 + 2x)) = 0 ((-7 + 14x) + 6x * (-1 + 2x)) = 0 (-7 + 14x + (-1 * 6x + 2x * 6x)) = 0 (-7 + 14x + (-6x + 12x2)) = 0 Combine like terms: 14x + -6x = 8x (-7 + 8x + 12x2) = 0 Solving -7 + 8x + 12x2 = 0 Solving for variable 'x'. Factor a trinomial. (-7 + -6x)(1 + -2x) = 0Subproblem 1
Set the factor '(-7 + -6x)' equal to zero and attempt to solve: Simplifying -7 + -6x = 0 Solving -7 + -6x = 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 + -6x = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -6x = 0 + 7 -6x = 0 + 7 Combine like terms: 0 + 7 = 7 -6x = 7 Divide each side by '-6'. x = -1.166666667 Simplifying x = -1.166666667Subproblem 2
Set the factor '(1 + -2x)' equal to zero and attempt to solve: Simplifying 1 + -2x = 0 Solving 1 + -2x = 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 + -2x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2x = 0 + -1 -2x = 0 + -1 Combine like terms: 0 + -1 = -1 -2x = -1 Divide each side by '-2'. x = 0.5 Simplifying x = 0.5Solution
x = {-1.166666667, 0.5}
