Simplifying x2 + -18x + 69 = 0 Reorder the terms: 69 + -18x + x2 = 0 Solving 69 + -18x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-69' to each side of the equation. 69 + -18x + -69 + x2 = 0 + -69 Reorder the terms: 69 + -69 + -18x + x2 = 0 + -69 Combine like terms: 69 + -69 = 0 0 + -18x + x2 = 0 + -69 -18x + x2 = 0 + -69 Combine like terms: 0 + -69 = -69 -18x + x2 = -69 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 = -69 + 81 Reorder the terms: 81 + -18x + x2 = -69 + 81 Combine like terms: -69 + 81 = 12 81 + -18x + x2 = 12 Factor a perfect square on the left side: (x + -9)(x + -9) = 12 Calculate the square root of the right side: 3.464101615 Break this problem into two subproblems by setting (x + -9) equal to 3.464101615 and -3.464101615.Subproblem 1
x + -9 = 3.464101615 Simplifying x + -9 = 3.464101615 Reorder the terms: -9 + x = 3.464101615 Solving -9 + x = 3.464101615 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 = 3.464101615 + 9 Combine like terms: -9 + 9 = 0 0 + x = 3.464101615 + 9 x = 3.464101615 + 9 Combine like terms: 3.464101615 + 9 = 12.464101615 x = 12.464101615 Simplifying x = 12.464101615Subproblem 2
x + -9 = -3.464101615 Simplifying x + -9 = -3.464101615 Reorder the terms: -9 + x = -3.464101615 Solving -9 + x = -3.464101615 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 = -3.464101615 + 9 Combine like terms: -9 + 9 = 0 0 + x = -3.464101615 + 9 x = -3.464101615 + 9 Combine like terms: -3.464101615 + 9 = 5.535898385 x = 5.535898385 Simplifying x = 5.535898385Solution
