Simplifying 2x2 + -10x + -11 = 0 Reorder the terms: -11 + -10x + 2x2 = 0 Solving -11 + -10x + 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'. -5.5 + -5x + x2 = 0 Move the constant term to the right: Add '5.5' to each side of the equation. -5.5 + -5x + 5.5 + x2 = 0 + 5.5 Reorder the terms: -5.5 + 5.5 + -5x + x2 = 0 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + -5x + x2 = 0 + 5.5 -5x + x2 = 0 + 5.5 Combine like terms: 0 + 5.5 = 5.5 -5x + x2 = 5.5 The x term is -5x. Take half its coefficient (-2.5). Square it (6.25) and add it to both sides. Add '6.25' to each side of the equation. -5x + 6.25 + x2 = 5.5 + 6.25 Reorder the terms: 6.25 + -5x + x2 = 5.5 + 6.25 Combine like terms: 5.5 + 6.25 = 11.75 6.25 + -5x + x2 = 11.75 Factor a perfect square on the left side: (x + -2.5)(x + -2.5) = 11.75 Calculate the square root of the right side: 3.4278273 Break this problem into two subproblems by setting (x + -2.5) equal to 3.4278273 and -3.4278273.Subproblem 1
x + -2.5 = 3.4278273 Simplifying x + -2.5 = 3.4278273 Reorder the terms: -2.5 + x = 3.4278273 Solving -2.5 + x = 3.4278273 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = 3.4278273 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = 3.4278273 + 2.5 x = 3.4278273 + 2.5 Combine like terms: 3.4278273 + 2.5 = 5.9278273 x = 5.9278273 Simplifying x = 5.9278273Subproblem 2
x + -2.5 = -3.4278273 Simplifying x + -2.5 = -3.4278273 Reorder the terms: -2.5 + x = -3.4278273 Solving -2.5 + x = -3.4278273 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2.5' to each side of the equation. -2.5 + 2.5 + x = -3.4278273 + 2.5 Combine like terms: -2.5 + 2.5 = 0.0 0.0 + x = -3.4278273 + 2.5 x = -3.4278273 + 2.5 Combine like terms: -3.4278273 + 2.5 = -0.9278273 x = -0.9278273 Simplifying x = -0.9278273Solution
The solution to the problem is based on the solutions from the subproblems. x = {5.9278273, -0.9278273}
