Simplifying x2 + 22x + 121 = 24 Reorder the terms: 121 + 22x + x2 = 24 Solving 121 + 22x + x2 = 24 Solving for variable 'x'. Reorder the terms: 121 + -24 + 22x + x2 = 24 + -24 Combine like terms: 121 + -24 = 97 97 + 22x + x2 = 24 + -24 Combine like terms: 24 + -24 = 0 97 + 22x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-97' to each side of the equation. 97 + 22x + -97 + x2 = 0 + -97 Reorder the terms: 97 + -97 + 22x + x2 = 0 + -97 Combine like terms: 97 + -97 = 0 0 + 22x + x2 = 0 + -97 22x + x2 = 0 + -97 Combine like terms: 0 + -97 = -97 22x + x2 = -97 The x term is 22x. Take half its coefficient (11). Square it (121) and add it to both sides. Add '121' to each side of the equation. 22x + 121 + x2 = -97 + 121 Reorder the terms: 121 + 22x + x2 = -97 + 121 Combine like terms: -97 + 121 = 24 121 + 22x + x2 = 24 Factor a perfect square on the left side: (x + 11)(x + 11) = 24 Calculate the square root of the right side: 4.898979486 Break this problem into two subproblems by setting (x + 11) equal to 4.898979486 and -4.898979486.Subproblem 1
x + 11 = 4.898979486 Simplifying x + 11 = 4.898979486 Reorder the terms: 11 + x = 4.898979486 Solving 11 + x = 4.898979486 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + x = 4.898979486 + -11 Combine like terms: 11 + -11 = 0 0 + x = 4.898979486 + -11 x = 4.898979486 + -11 Combine like terms: 4.898979486 + -11 = -6.101020514 x = -6.101020514 Simplifying x = -6.101020514Subproblem 2
x + 11 = -4.898979486 Simplifying x + 11 = -4.898979486 Reorder the terms: 11 + x = -4.898979486 Solving 11 + x = -4.898979486 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11' to each side of the equation. 11 + -11 + x = -4.898979486 + -11 Combine like terms: 11 + -11 = 0 0 + x = -4.898979486 + -11 x = -4.898979486 + -11 Combine like terms: -4.898979486 + -11 = -15.898979486 x = -15.898979486 Simplifying x = -15.898979486Solution
