Simplifying 2x2 + 45x + 125 = 0 Reorder the terms: 125 + 45x + 2x2 = 0 Solving 125 + 45x + 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'. 62.5 + 22.5x + x2 = 0 Move the constant term to the right: Add '-62.5' to each side of the equation. 62.5 + 22.5x + -62.5 + x2 = 0 + -62.5 Reorder the terms: 62.5 + -62.5 + 22.5x + x2 = 0 + -62.5 Combine like terms: 62.5 + -62.5 = 0.0 0.0 + 22.5x + x2 = 0 + -62.5 22.5x + x2 = 0 + -62.5 Combine like terms: 0 + -62.5 = -62.5 22.5x + x2 = -62.5 The x term is 22.5x. Take half its coefficient (11.25). Square it (126.5625) and add it to both sides. Add '126.5625' to each side of the equation. 22.5x + 126.5625 + x2 = -62.5 + 126.5625 Reorder the terms: 126.5625 + 22.5x + x2 = -62.5 + 126.5625 Combine like terms: -62.5 + 126.5625 = 64.0625 126.5625 + 22.5x + x2 = 64.0625 Factor a perfect square on the left side: (x + 11.25)(x + 11.25) = 64.0625 Calculate the square root of the right side: 8.003905297 Break this problem into two subproblems by setting (x + 11.25) equal to 8.003905297 and -8.003905297.Subproblem 1
x + 11.25 = 8.003905297 Simplifying x + 11.25 = 8.003905297 Reorder the terms: 11.25 + x = 8.003905297 Solving 11.25 + x = 8.003905297 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11.25' to each side of the equation. 11.25 + -11.25 + x = 8.003905297 + -11.25 Combine like terms: 11.25 + -11.25 = 0.00 0.00 + x = 8.003905297 + -11.25 x = 8.003905297 + -11.25 Combine like terms: 8.003905297 + -11.25 = -3.246094703 x = -3.246094703 Simplifying x = -3.246094703Subproblem 2
x + 11.25 = -8.003905297 Simplifying x + 11.25 = -8.003905297 Reorder the terms: 11.25 + x = -8.003905297 Solving 11.25 + x = -8.003905297 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-11.25' to each side of the equation. 11.25 + -11.25 + x = -8.003905297 + -11.25 Combine like terms: 11.25 + -11.25 = 0.00 0.00 + x = -8.003905297 + -11.25 x = -8.003905297 + -11.25 Combine like terms: -8.003905297 + -11.25 = -19.253905297 x = -19.253905297 Simplifying x = -19.253905297Solution
The solution to the problem is based on the solutions from the subproblems. x = {-3.246094703, -19.253905297}
