Simplifying 3x2 = 6 + -7x Solving 3x2 = 6 + -7x Solving for variable 'x'. Reorder the terms: -6 + 7x + 3x2 = 6 + -7x + -6 + 7x Reorder the terms: -6 + 7x + 3x2 = 6 + -6 + -7x + 7x Combine like terms: 6 + -6 = 0 -6 + 7x + 3x2 = 0 + -7x + 7x -6 + 7x + 3x2 = -7x + 7x Combine like terms: -7x + 7x = 0 -6 + 7x + 3x2 = 0 Factor a trinomial. (-3 + -1x)(2 + -3x) = 0Subproblem 1
Set the factor '(-3 + -1x)' equal to zero and attempt to solve: Simplifying -3 + -1x = 0 Solving -3 + -1x = 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 + -1x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -1x = 0 + 3 -1x = 0 + 3 Combine like terms: 0 + 3 = 3 -1x = 3 Divide each side by '-1'. x = -3 Simplifying x = -3Subproblem 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, 0.6666666667}
