Simplifying x2 + 21x + -22 = 3x + -10 Reorder the terms: -22 + 21x + x2 = 3x + -10 Reorder the terms: -22 + 21x + x2 = -10 + 3x Solving -22 + 21x + x2 = -10 + 3x Solving for variable 'x'. Reorder the terms: -22 + 10 + 21x + -3x + x2 = -10 + 3x + 10 + -3x Combine like terms: -22 + 10 = -12 -12 + 21x + -3x + x2 = -10 + 3x + 10 + -3x Combine like terms: 21x + -3x = 18x -12 + 18x + x2 = -10 + 3x + 10 + -3x Reorder the terms: -12 + 18x + x2 = -10 + 10 + 3x + -3x Combine like terms: -10 + 10 = 0 -12 + 18x + x2 = 0 + 3x + -3x -12 + 18x + x2 = 3x + -3x Combine like terms: 3x + -3x = 0 -12 + 18x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '12' to each side of the equation. -12 + 18x + 12 + x2 = 0 + 12 Reorder the terms: -12 + 12 + 18x + x2 = 0 + 12 Combine like terms: -12 + 12 = 0 0 + 18x + x2 = 0 + 12 18x + x2 = 0 + 12 Combine like terms: 0 + 12 = 12 18x + x2 = 12 The x term is 18x. Take half its coefficient (9). Square it (81) and add it to both sides. Add '81' to each side of the equation. 18x + 81 + x2 = 12 + 81 Reorder the terms: 81 + 18x + x2 = 12 + 81 Combine like terms: 12 + 81 = 93 81 + 18x + x2 = 93 Factor a perfect square on the left side: (x + 9)(x + 9) = 93 Calculate the square root of the right side: 9.643650761 Break this problem into two subproblems by setting (x + 9) equal to 9.643650761 and -9.643650761.Subproblem 1
x + 9 = 9.643650761 Simplifying x + 9 = 9.643650761 Reorder the terms: 9 + x = 9.643650761 Solving 9 + x = 9.643650761 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x = 9.643650761 + -9 Combine like terms: 9 + -9 = 0 0 + x = 9.643650761 + -9 x = 9.643650761 + -9 Combine like terms: 9.643650761 + -9 = 0.643650761 x = 0.643650761 Simplifying x = 0.643650761Subproblem 2
x + 9 = -9.643650761 Simplifying x + 9 = -9.643650761 Reorder the terms: 9 + x = -9.643650761 Solving 9 + x = -9.643650761 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + x = -9.643650761 + -9 Combine like terms: 9 + -9 = 0 0 + x = -9.643650761 + -9 x = -9.643650761 + -9 Combine like terms: -9.643650761 + -9 = -18.643650761 x = -18.643650761 Simplifying x = -18.643650761Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.643650761, -18.643650761}
