Simplifying x(2x + 3) + 6x2 = 9x + -1 Reorder the terms: x(3 + 2x) + 6x2 = 9x + -1 (3 * x + 2x * x) + 6x2 = 9x + -1 (3x + 2x2) + 6x2 = 9x + -1 Combine like terms: 2x2 + 6x2 = 8x2 3x + 8x2 = 9x + -1 Reorder the terms: 3x + 8x2 = -1 + 9x Solving 3x + 8x2 = -1 + 9x Solving for variable 'x'. Reorder the terms: 1 + 3x + -9x + 8x2 = -1 + 9x + 1 + -9x Combine like terms: 3x + -9x = -6x 1 + -6x + 8x2 = -1 + 9x + 1 + -9x Reorder the terms: 1 + -6x + 8x2 = -1 + 1 + 9x + -9x Combine like terms: -1 + 1 = 0 1 + -6x + 8x2 = 0 + 9x + -9x 1 + -6x + 8x2 = 9x + -9x Combine like terms: 9x + -9x = 0 1 + -6x + 8x2 = 0 Factor a trinomial. (1 + -4x)(1 + -2x) = 0Subproblem 1
Set the factor '(1 + -4x)' equal to zero and attempt to solve: Simplifying 1 + -4x = 0 Solving 1 + -4x = 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 + -4x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -4x = 0 + -1 -4x = 0 + -1 Combine like terms: 0 + -1 = -1 -4x = -1 Divide each side by '-4'. x = 0.25 Simplifying x = 0.25Subproblem 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 = {0.25, 0.5}
