Simplifying 5x2 = 9x + 2 Reorder the terms: 5x2 = 2 + 9x Solving 5x2 = 2 + 9x Solving for variable 'x'. Reorder the terms: -2 + -9x + 5x2 = 2 + 9x + -2 + -9x Reorder the terms: -2 + -9x + 5x2 = 2 + -2 + 9x + -9x Combine like terms: 2 + -2 = 0 -2 + -9x + 5x2 = 0 + 9x + -9x -2 + -9x + 5x2 = 9x + -9x Combine like terms: 9x + -9x = 0 -2 + -9x + 5x2 = 0 Factor a trinomial. (-1 + -5x)(2 + -1x) = 0Subproblem 1
Set the factor '(-1 + -5x)' equal to zero and attempt to solve: Simplifying -1 + -5x = 0 Solving -1 + -5x = 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 + -5x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -5x = 0 + 1 -5x = 0 + 1 Combine like terms: 0 + 1 = 1 -5x = 1 Divide each side by '-5'. x = -0.2 Simplifying x = -0.2Subproblem 2
Set the factor '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 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 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Divide each side by '-1'. x = 2 Simplifying x = 2Solution
x = {-0.2, 2}
