Simplifying x2 + 17x = 90 Reorder the terms: 17x + x2 = 90 Solving 17x + x2 = 90 Solving for variable 'x'. Reorder the terms: -90 + 17x + x2 = 90 + -90 Combine like terms: 90 + -90 = 0 -90 + 17x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '90' to each side of the equation. -90 + 17x + 90 + x2 = 0 + 90 Reorder the terms: -90 + 90 + 17x + x2 = 0 + 90 Combine like terms: -90 + 90 = 0 0 + 17x + x2 = 0 + 90 17x + x2 = 0 + 90 Combine like terms: 0 + 90 = 90 17x + x2 = 90 The x term is 17x. Take half its coefficient (8.5). Square it (72.25) and add it to both sides. Add '72.25' to each side of the equation. 17x + 72.25 + x2 = 90 + 72.25 Reorder the terms: 72.25 + 17x + x2 = 90 + 72.25 Combine like terms: 90 + 72.25 = 162.25 72.25 + 17x + x2 = 162.25 Factor a perfect square on the left side: (x + 8.5)(x + 8.5) = 162.25 Calculate the square root of the right side: 12.737739203 Break this problem into two subproblems by setting (x + 8.5) equal to 12.737739203 and -12.737739203.Subproblem 1
x + 8.5 = 12.737739203 Simplifying x + 8.5 = 12.737739203 Reorder the terms: 8.5 + x = 12.737739203 Solving 8.5 + x = 12.737739203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + x = 12.737739203 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = 12.737739203 + -8.5 x = 12.737739203 + -8.5 Combine like terms: 12.737739203 + -8.5 = 4.237739203 x = 4.237739203 Simplifying x = 4.237739203Subproblem 2
x + 8.5 = -12.737739203 Simplifying x + 8.5 = -12.737739203 Reorder the terms: 8.5 + x = -12.737739203 Solving 8.5 + x = -12.737739203 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-8.5' to each side of the equation. 8.5 + -8.5 + x = -12.737739203 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + x = -12.737739203 + -8.5 x = -12.737739203 + -8.5 Combine like terms: -12.737739203 + -8.5 = -21.237739203 x = -21.237739203 Simplifying x = -21.237739203Solution
