Simplifying 14 = x(3x + 19) Reorder the terms: 14 = x(19 + 3x) 14 = (19 * x + 3x * x) 14 = (19x + 3x2) Solving 14 = 19x + 3x2 Solving for variable 'x'. Reorder the terms: 14 + -19x + -3x2 = 19x + -19x + 3x2 + -3x2 Combine like terms: 19x + -19x = 0 14 + -19x + -3x2 = 0 + 3x2 + -3x2 14 + -19x + -3x2 = 3x2 + -3x2 Combine like terms: 3x2 + -3x2 = 0 14 + -19x + -3x2 = 0 Factor a trinomial. (2 + -3x)(7 + x) = 0Subproblem 1
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 = 0.6666666667Subproblem 2
Set the factor '(7 + x)' equal to zero and attempt to solve: Simplifying 7 + x = 0 Solving 7 + x = 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 + x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + x = 0 + -7 x = 0 + -7 Combine like terms: 0 + -7 = -7 x = -7 Simplifying x = -7Solution
x = {0.6666666667, -7}
