Simplifying x2 + 9x + -111 = 0 Reorder the terms: -111 + 9x + x2 = 0 Solving -111 + 9x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '111' to each side of the equation. -111 + 9x + 111 + x2 = 0 + 111 Reorder the terms: -111 + 111 + 9x + x2 = 0 + 111 Combine like terms: -111 + 111 = 0 0 + 9x + x2 = 0 + 111 9x + x2 = 0 + 111 Combine like terms: 0 + 111 = 111 9x + x2 = 111 The x term is 9x. Take half its coefficient (4.5). Square it (20.25) and add it to both sides. Add '20.25' to each side of the equation. 9x + 20.25 + x2 = 111 + 20.25 Reorder the terms: 20.25 + 9x + x2 = 111 + 20.25 Combine like terms: 111 + 20.25 = 131.25 20.25 + 9x + x2 = 131.25 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 131.25 Calculate the square root of the right side: 11.456439237 Break this problem into two subproblems by setting (x + 4.5) equal to 11.456439237 and -11.456439237.Subproblem 1
x + 4.5 = 11.456439237 Simplifying x + 4.5 = 11.456439237 Reorder the terms: 4.5 + x = 11.456439237 Solving 4.5 + x = 11.456439237 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = 11.456439237 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 11.456439237 + -4.5 x = 11.456439237 + -4.5 Combine like terms: 11.456439237 + -4.5 = 6.956439237 x = 6.956439237 Simplifying x = 6.956439237Subproblem 2
x + 4.5 = -11.456439237 Simplifying x + 4.5 = -11.456439237 Reorder the terms: 4.5 + x = -11.456439237 Solving 4.5 + x = -11.456439237 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4.5' to each side of the equation. 4.5 + -4.5 + x = -11.456439237 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -11.456439237 + -4.5 x = -11.456439237 + -4.5 Combine like terms: -11.456439237 + -4.5 = -15.956439237 x = -15.956439237 Simplifying x = -15.956439237Solution
