Simplifying 56 = (3x + 2) * x Reorder the terms: 56 = (2 + 3x) * x Reorder the terms for easier multiplication: 56 = x(2 + 3x) 56 = (2 * x + 3x * x) 56 = (2x + 3x2) Solving 56 = 2x + 3x2 Solving for variable 'x'. Reorder the terms: 56 + -2x + -3x2 = 2x + -2x + 3x2 + -3x2 Combine like terms: 2x + -2x = 0 56 + -2x + -3x2 = 0 + 3x2 + -3x2 56 + -2x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 56 + -2x + -3x2 = 0 Factor a trinomial. (4 + -1x)(14 + 3x) = 0Subproblem 1
Set the factor '(4 + -1x)' equal to zero and attempt to solve: Simplifying 4 + -1x = 0 Solving 4 + -1x = 0 Move all terms containing x to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -1x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -1x = 0 + -4 -1x = 0 + -4 Combine like terms: 0 + -4 = -4 -1x = -4 Divide each side by '-1'. x = 4 Simplifying x = 4Subproblem 2
Set the factor '(14 + 3x)' equal to zero and attempt to solve: Simplifying 14 + 3x = 0 Solving 14 + 3x = 0 Move all terms containing x to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + 3x = 0 + -14 Combine like terms: 14 + -14 = 0 0 + 3x = 0 + -14 3x = 0 + -14 Combine like terms: 0 + -14 = -14 3x = -14 Divide each side by '3'. x = -4.666666667 Simplifying x = -4.666666667Solution
x = {4, -4.666666667}
