Simplifying 8x2 = 30x + 17 Reorder the terms: 8x2 = 17 + 30x Solving 8x2 = 17 + 30x Solving for variable 'x'. Reorder the terms: -17 + -30x + 8x2 = 17 + 30x + -17 + -30x Reorder the terms: -17 + -30x + 8x2 = 17 + -17 + 30x + -30x Combine like terms: 17 + -17 = 0 -17 + -30x + 8x2 = 0 + 30x + -30x -17 + -30x + 8x2 = 30x + -30x Combine like terms: 30x + -30x = 0 -17 + -30x + 8x2 = 0 Factor a trinomial. (-1 + -2x)(17 + -4x) = 0Subproblem 1
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 = -0.5Subproblem 2
Set the factor '(17 + -4x)' equal to zero and attempt to solve: Simplifying 17 + -4x = 0 Solving 17 + -4x = 0 Move all terms containing x to the left, all other terms to the right. Add '-17' to each side of the equation. 17 + -17 + -4x = 0 + -17 Combine like terms: 17 + -17 = 0 0 + -4x = 0 + -17 -4x = 0 + -17 Combine like terms: 0 + -17 = -17 -4x = -17 Divide each side by '-4'. x = 4.25 Simplifying x = 4.25Solution
x = {-0.5, 4.25}
