Simplifying 10x2 + -5x + -11 = 0 Reorder the terms: -11 + -5x + 10x2 = 0 Solving -11 + -5x + 10x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 10 the coefficient of the squared term: Divide each side by '10'. -1.1 + -0.5x + x2 = 0 Move the constant term to the right: Add '1.1' to each side of the equation. -1.1 + -0.5x + 1.1 + x2 = 0 + 1.1 Reorder the terms: -1.1 + 1.1 + -0.5x + x2 = 0 + 1.1 Combine like terms: -1.1 + 1.1 = 0.0 0.0 + -0.5x + x2 = 0 + 1.1 -0.5x + x2 = 0 + 1.1 Combine like terms: 0 + 1.1 = 1.1 -0.5x + x2 = 1.1 The x term is -0.5x. Take half its coefficient (-0.25). Square it (0.0625) and add it to both sides. Add '0.0625' to each side of the equation. -0.5x + 0.0625 + x2 = 1.1 + 0.0625 Reorder the terms: 0.0625 + -0.5x + x2 = 1.1 + 0.0625 Combine like terms: 1.1 + 0.0625 = 1.1625 0.0625 + -0.5x + x2 = 1.1625 Factor a perfect square on the left side: (x + -0.25)(x + -0.25) = 1.1625 Calculate the square root of the right side: 1.078192933 Break this problem into two subproblems by setting (x + -0.25) equal to 1.078192933 and -1.078192933.Subproblem 1
x + -0.25 = 1.078192933 Simplifying x + -0.25 = 1.078192933 Reorder the terms: -0.25 + x = 1.078192933 Solving -0.25 + x = 1.078192933 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = 1.078192933 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = 1.078192933 + 0.25 x = 1.078192933 + 0.25 Combine like terms: 1.078192933 + 0.25 = 1.328192933 x = 1.328192933 Simplifying x = 1.328192933Subproblem 2
x + -0.25 = -1.078192933 Simplifying x + -0.25 = -1.078192933 Reorder the terms: -0.25 + x = -1.078192933 Solving -0.25 + x = -1.078192933 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.25' to each side of the equation. -0.25 + 0.25 + x = -1.078192933 + 0.25 Combine like terms: -0.25 + 0.25 = 0.00 0.00 + x = -1.078192933 + 0.25 x = -1.078192933 + 0.25 Combine like terms: -1.078192933 + 0.25 = -0.828192933 x = -0.828192933 Simplifying x = -0.828192933Solution
