Simplifying 2x2 = 13x + -11 Reorder the terms: 2x2 = -11 + 13x Solving 2x2 = -11 + 13x Solving for variable 'x'. Reorder the terms: 11 + -13x + 2x2 = -11 + 13x + 11 + -13x Reorder the terms: 11 + -13x + 2x2 = -11 + 11 + 13x + -13x Combine like terms: -11 + 11 = 0 11 + -13x + 2x2 = 0 + 13x + -13x 11 + -13x + 2x2 = 13x + -13x Combine like terms: 13x + -13x = 0 11 + -13x + 2x2 = 0 Factor a trinomial. (1 + -1x)(11 + -2x) = 0Subproblem 1
Set the factor '(1 + -1x)' equal to zero and attempt to solve: Simplifying 1 + -1x = 0 Solving 1 + -1x = 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 + -1x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1x = 0 + -1 -1x = 0 + -1 Combine like terms: 0 + -1 = -1 -1x = -1 Divide each side by '-1'. x = 1 Simplifying x = 1Subproblem 2
Set the factor '(11 + -2x)' equal to zero and attempt to solve: Simplifying 11 + -2x = 0 Solving 11 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + -2x = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -2x = 0 + -11 -2x = 0 + -11 Combine like terms: 0 + -11 = -11 -2x = -11 Divide each side by '-2'. x = 5.5 Simplifying x = 5.5Solution
x = {1, 5.5}
