Simplifying x2 + -5x + -91 = 0 Reorder the terms: -91 + -5x + x2 = 0 Solving -91 + -5x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '91' to each side of the equation. -91 + -5x + 91 + x2 = 0 + 91 Reorder the terms: -91 + 91 + -5x + x2 = 0 + 91 Combine like terms: -91 + 91 = 0 0 + -5x + x2 = 0 + 91 -5x + x2 = 0 + 91 Combine like terms: 0 + 91 = 91 -5x + x2 = 91 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 91 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 91 + 6.25 Combine like terms: 91 + 6.25 = 97.25 6.25 + -5x + x2 = 97.25 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 97.25 Calculate the square root of the right side: 9.861541462 Break this problem into two subproblems by setting (x + -2.5) equal to 9.861541462 and -9.861541462.Subproblem 1
x + -2.5 = 9.861541462 Simplifying x + -2.5 = 9.861541462 Reorder the terms: -2.5 + x = 9.861541462 Solving -2.5 + x = 9.861541462 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 9.861541462 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 9.861541462 + 2.5 x = 9.861541462 + 2.5 Combine like terms: 9.861541462 + 2.5 = 12.361541462 x = 12.361541462 Simplifying x = 12.361541462Subproblem 2
x + -2.5 = -9.861541462 Simplifying x + -2.5 = -9.861541462 Reorder the terms: -2.5 + x = -9.861541462 Solving -2.5 + x = -9.861541462 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -9.861541462 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -9.861541462 + 2.5 x = -9.861541462 + 2.5 Combine like terms: -9.861541462 + 2.5 = -7.361541462 x = -7.361541462 Simplifying x = -7.361541462Solution
