Simplifying 2x2 + 9x + -750 = 0 Reorder the terms: -750 + 9x + 2x2 = 0 Solving -750 + 9x + 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'. -375 + 4.5x + x2 = 0 Move the constant term to the right: Add '375' to each side of the equation. -375 + 4.5x + 375 + x2 = 0 + 375 Reorder the terms: -375 + 375 + 4.5x + x2 = 0 + 375 Combine like terms: -375 + 375 = 0 0 + 4.5x + x2 = 0 + 375 4.5x + x2 = 0 + 375 Combine like terms: 0 + 375 = 375 4.5x + x2 = 375 The x term is 4.5x. Take half its coefficient (2.25). Square it (5.0625) and add it to both sides. Add '5.0625' to each side of the equation. 4.5x + 5.0625 + x2 = 375 + 5.0625 Reorder the terms: 5.0625 + 4.5x + x2 = 375 + 5.0625 Combine like terms: 375 + 5.0625 = 380.0625 5.0625 + 4.5x + x2 = 380.0625 Factor a perfect square on the left side: (x + 2.25)(x + 2.25) = 380.0625 Calculate the square root of the right side: 19.495191715 Break this problem into two subproblems by setting (x + 2.25) equal to 19.495191715 and -19.495191715.Subproblem 1
x + 2.25 = 19.495191715 Simplifying x + 2.25 = 19.495191715 Reorder the terms: 2.25 + x = 19.495191715 Solving 2.25 + x = 19.495191715 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = 19.495191715 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = 19.495191715 + -2.25 x = 19.495191715 + -2.25 Combine like terms: 19.495191715 + -2.25 = 17.245191715 x = 17.245191715 Simplifying x = 17.245191715Subproblem 2
x + 2.25 = -19.495191715 Simplifying x + 2.25 = -19.495191715 Reorder the terms: 2.25 + x = -19.495191715 Solving 2.25 + x = -19.495191715 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2.25' to each side of the equation. 2.25 + -2.25 + x = -19.495191715 + -2.25 Combine like terms: 2.25 + -2.25 = 0.00 0.00 + x = -19.495191715 + -2.25 x = -19.495191715 + -2.25 Combine like terms: -19.495191715 + -2.25 = -21.745191715 x = -21.745191715 Simplifying x = -21.745191715Solution
