Simplifying 8x2 = 22x + 63 Reorder the terms: 8x2 = 63 + 22x Solving 8x2 = 63 + 22x Solving for variable 'x'. Reorder the terms: -63 + -22x + 8x2 = 63 + 22x + -63 + -22x Reorder the terms: -63 + -22x + 8x2 = 63 + -63 + 22x + -22x Combine like terms: 63 + -63 = 0 -63 + -22x + 8x2 = 0 + 22x + -22x -63 + -22x + 8x2 = 22x + -22x Combine like terms: 22x + -22x = 0 -63 + -22x + 8x2 = 0 Factor a trinomial. (-7 + -4x)(9 + -2x) = 0Subproblem 1
Set the factor '(-7 + -4x)' equal to zero and attempt to solve: Simplifying -7 + -4x = 0 Solving -7 + -4x = 0 Move all terms containing x to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -4x = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -4x = 0 + 7 -4x = 0 + 7 Combine like terms: 0 + 7 = 7 -4x = 7 Divide each side by '-4'. x = -1.75 Simplifying x = -1.75Subproblem 2
Set the factor '(9 + -2x)' equal to zero and attempt to solve: Simplifying 9 + -2x = 0 Solving 9 + -2x = 0 Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -2x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -2x = 0 + -9 -2x = 0 + -9 Combine like terms: 0 + -9 = -9 -2x = -9 Divide each side by '-2'. x = 4.5 Simplifying x = 4.5Solution
x = {-1.75, 4.5}
