Simplifying 20x2 + 12x + -11 = 0 Reorder the terms: -11 + 12x + 20x2 = 0 Solving -11 + 12x + 20x2 = 0 Solving for variable 'x'. Factor a trinomial. (-11 + -10x)(1 + -2x) = 0Subproblem 1
Set the factor '(-11 + -10x)' equal to zero and attempt to solve: Simplifying -11 + -10x = 0 Solving -11 + -10x = 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 + -10x = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -10x = 0 + 11 -10x = 0 + 11 Combine like terms: 0 + 11 = 11 -10x = 11 Divide each side by '-10'. x = -1.1 Simplifying x = -1.1Subproblem 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 = {-1.1, 0.5}
