Simplifying x2 + 2x = 91 Reorder the terms: 2x + x2 = 91 Solving 2x + x2 = 91 Solving for variable 'x'. Reorder the terms: -91 + 2x + x2 = 91 + -91 Combine like terms: 91 + -91 = 0 -91 + 2x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '91' to each side of the equation. -91 + 2x + 91 + x2 = 0 + 91 Reorder the terms: -91 + 91 + 2x + x2 = 0 + 91 Combine like terms: -91 + 91 = 0 0 + 2x + x2 = 0 + 91 2x + x2 = 0 + 91 Combine like terms: 0 + 91 = 91 2x + x2 = 91 The x term is 2x. Take half its coefficient (1). Square it (1) and add it to both sides. Add '1' to each side of the equation. 2x + 1 + x2 = 91 + 1 Reorder the terms: 1 + 2x + x2 = 91 + 1 Combine like terms: 91 + 1 = 92 1 + 2x + x2 = 92 Factor a perfect square on the left side: (x + 1)(x + 1) = 92 Calculate the square root of the right side: 9.591663047 Break this problem into two subproblems by setting (x + 1) equal to 9.591663047 and -9.591663047.Subproblem 1
x + 1 = 9.591663047 Simplifying x + 1 = 9.591663047 Reorder the terms: 1 + x = 9.591663047 Solving 1 + x = 9.591663047 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = 9.591663047 + -1 Combine like terms: 1 + -1 = 0 0 + x = 9.591663047 + -1 x = 9.591663047 + -1 Combine like terms: 9.591663047 + -1 = 8.591663047 x = 8.591663047 Simplifying x = 8.591663047Subproblem 2
x + 1 = -9.591663047 Simplifying x + 1 = -9.591663047 Reorder the terms: 1 + x = -9.591663047 Solving 1 + x = -9.591663047 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + x = -9.591663047 + -1 Combine like terms: 1 + -1 = 0 0 + x = -9.591663047 + -1 x = -9.591663047 + -1 Combine like terms: -9.591663047 + -1 = -10.591663047 x = -10.591663047 Simplifying x = -10.591663047Solution
