Simplifying x2 + -18x + 74 = 13 Reorder the terms: 74 + -18x + x2 = 13 Solving 74 + -18x + x2 = 13 Solving for variable 'x'. Reorder the terms: 74 + -13 + -18x + x2 = 13 + -13 Combine like terms: 74 + -13 = 61 61 + -18x + x2 = 13 + -13 Combine like terms: 13 + -13 = 0 61 + -18x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '-61' to each side of the equation. 61 + -18x + -61 + x2 = 0 + -61 Reorder the terms: 61 + -61 + -18x + x2 = 0 + -61 Combine like terms: 61 + -61 = 0 0 + -18x + x2 = 0 + -61 -18x + x2 = 0 + -61 Combine like terms: 0 + -61 = -61 -18x + x2 = -61 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 = -61 + 81 Reorder the terms: 81 + -18x + x2 = -61 + 81 Combine like terms: -61 + 81 = 20 81 + -18x + x2 = 20 Factor a perfect square on the left side: (x + -9)(x + -9) = 20 Calculate the square root of the right side: 4.472135955 Break this problem into two subproblems by setting (x + -9) equal to 4.472135955 and -4.472135955.Subproblem 1
x + -9 = 4.472135955 Simplifying x + -9 = 4.472135955 Reorder the terms: -9 + x = 4.472135955 Solving -9 + x = 4.472135955 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 = 4.472135955 + 9 Combine like terms: -9 + 9 = 0 0 + x = 4.472135955 + 9 x = 4.472135955 + 9 Combine like terms: 4.472135955 + 9 = 13.472135955 x = 13.472135955 Simplifying x = 13.472135955Subproblem 2
x + -9 = -4.472135955 Simplifying x + -9 = -4.472135955 Reorder the terms: -9 + x = -4.472135955 Solving -9 + x = -4.472135955 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 = -4.472135955 + 9 Combine like terms: -9 + 9 = 0 0 + x = -4.472135955 + 9 x = -4.472135955 + 9 Combine like terms: -4.472135955 + 9 = 4.527864045 x = 4.527864045 Simplifying x = 4.527864045Solution
