Simplifying x2 + -10x + 21 = x + 3 Reorder the terms: 21 + -10x + x2 = x + 3 Reorder the terms: 21 + -10x + x2 = 3 + x Solving 21 + -10x + x2 = 3 + x Solving for variable 'x'. Reorder the terms: 21 + -3 + -10x + -1x + x2 = 3 + x + -3 + -1x Combine like terms: 21 + -3 = 18 18 + -10x + -1x + x2 = 3 + x + -3 + -1x Combine like terms: -10x + -1x = -11x 18 + -11x + x2 = 3 + x + -3 + -1x Reorder the terms: 18 + -11x + x2 = 3 + -3 + x + -1x Combine like terms: 3 + -3 = 0 18 + -11x + x2 = 0 + x + -1x 18 + -11x + x2 = x + -1x Combine like terms: x + -1x = 0 18 + -11x + x2 = 0 Factor a trinomial. (2 + -1x)(9 + -1x) = 0Subproblem 1
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 = 2Subproblem 2
Set the factor '(9 + -1x)' equal to zero and attempt to solve: Simplifying 9 + -1x = 0 Solving 9 + -1x = 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 + -1x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1x = 0 + -9 -1x = 0 + -9 Combine like terms: 0 + -9 = -9 -1x = -9 Divide each side by '-1'. x = 9 Simplifying x = 9Solution
x = {2, 9}
