Simplifying 2x2 + 18x + 17 = 0 Reorder the terms: 17 + 18x + 2x2 = 0 Solving 17 + 18x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. 8.5 + 9x + x2 = 0 Move the constant term to the right: Add '-8.5' to each side of the equation. 8.5 + 9x + -8.5 + x2 = 0 + -8.5 Reorder the terms: 8.5 + -8.5 + 9x + x2 = 0 + -8.5 Combine like terms: 8.5 + -8.5 = 0.0 0.0 + 9x + x2 = 0 + -8.5 9x + x2 = 0 + -8.5 Combine like terms: 0 + -8.5 = -8.5 9x + x2 = -8.5 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 = -8.5 + 20.25 Reorder the terms: 20.25 + 9x + x2 = -8.5 + 20.25 Combine like terms: -8.5 + 20.25 = 11.75 20.25 + 9x + x2 = 11.75 Factor a perfect square on the left side: (x + 4.5)(x + 4.5) = 11.75 Calculate the square root of the right side: 3.4278273 Break this problem into two subproblems by setting (x + 4.5) equal to 3.4278273 and -3.4278273.Subproblem 1
x + 4.5 = 3.4278273 Simplifying x + 4.5 = 3.4278273 Reorder the terms: 4.5 + x = 3.4278273 Solving 4.5 + x = 3.4278273 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 = 3.4278273 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = 3.4278273 + -4.5 x = 3.4278273 + -4.5 Combine like terms: 3.4278273 + -4.5 = -1.0721727 x = -1.0721727 Simplifying x = -1.0721727Subproblem 2
x + 4.5 = -3.4278273 Simplifying x + 4.5 = -3.4278273 Reorder the terms: 4.5 + x = -3.4278273 Solving 4.5 + x = -3.4278273 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 = -3.4278273 + -4.5 Combine like terms: 4.5 + -4.5 = 0.0 0.0 + x = -3.4278273 + -4.5 x = -3.4278273 + -4.5 Combine like terms: -3.4278273 + -4.5 = -7.9278273 x = -7.9278273 Simplifying x = -7.9278273Solution
The solution to the problem is based on the solutions from the subproblems. x = {-1.0721727, -7.9278273}
