Simplifying 91 = (2x + 2)(x + 1) Reorder the terms: 91 = (2 + 2x)(x + 1) Reorder the terms: 91 = (2 + 2x)(1 + x) Multiply (2 + 2x) * (1 + x) 91 = (2(1 + x) + 2x * (1 + x)) 91 = ((1 * 2 + x * 2) + 2x * (1 + x)) 91 = ((2 + 2x) + 2x * (1 + x)) 91 = (2 + 2x + (1 * 2x + x * 2x)) 91 = (2 + 2x + (2x + 2x2)) Combine like terms: 2x + 2x = 4x 91 = (2 + 4x + 2x2) Solving 91 = 2 + 4x + 2x2 Solving for variable 'x'. Combine like terms: 91 + -2 = 89 89 + -4x + -2x2 = 2 + 4x + 2x2 + -2 + -4x + -2x2 Reorder the terms: 89 + -4x + -2x2 = 2 + -2 + 4x + -4x + 2x2 + -2x2 Combine like terms: 2 + -2 = 0 89 + -4x + -2x2 = 0 + 4x + -4x + 2x2 + -2x2 89 + -4x + -2x2 = 4x + -4x + 2x2 + -2x2 Combine like terms: 4x + -4x = 0 89 + -4x + -2x2 = 0 + 2x2 + -2x2 89 + -4x + -2x2 = 2x2 + -2x2 Combine like terms: 2x2 + -2x2 = 0 89 + -4x + -2x2 = 0 Begin completing the square. Divide all terms by -2 the coefficient of the squared term: Divide each side by '-2'. -44.5 + 2x + x2 = 0 Move the constant term to the right: Add '44.5' to each side of the equation. -44.5 + 2x + 44.5 + x2 = 0 + 44.5 Reorder the terms: -44.5 + 44.5 + 2x + x2 = 0 + 44.5 Combine like terms: -44.5 + 44.5 = 0.0 0.0 + 2x + x2 = 0 + 44.5 2x + x2 = 0 + 44.5 Combine like terms: 0 + 44.5 = 44.5 2x + x2 = 44.5 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 = 44.5 + 1 Reorder the terms: 1 + 2x + x2 = 44.5 + 1 Combine like terms: 44.5 + 1 = 45.5 1 + 2x + x2 = 45.5 Factor a perfect square on the left side: (x + 1)(x + 1) = 45.5 Calculate the square root of the right side: 6.745368782 Break this problem into two subproblems by setting (x + 1) equal to 6.745368782 and -6.745368782.Subproblem 1
x + 1 = 6.745368782 Simplifying x + 1 = 6.745368782 Reorder the terms: 1 + x = 6.745368782 Solving 1 + x = 6.745368782 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 = 6.745368782 + -1 Combine like terms: 1 + -1 = 0 0 + x = 6.745368782 + -1 x = 6.745368782 + -1 Combine like terms: 6.745368782 + -1 = 5.745368782 x = 5.745368782 Simplifying x = 5.745368782Subproblem 2
x + 1 = -6.745368782 Simplifying x + 1 = -6.745368782 Reorder the terms: 1 + x = -6.745368782 Solving 1 + x = -6.745368782 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 = -6.745368782 + -1 Combine like terms: 1 + -1 = 0 0 + x = -6.745368782 + -1 x = -6.745368782 + -1 Combine like terms: -6.745368782 + -1 = -7.745368782 x = -7.745368782 Simplifying x = -7.745368782Solution
