Simplifying 10x2 + -1x + -81 = 0 Reorder the terms: -81 + -1x + 10x2 = 0 Solving -81 + -1x + 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'. -8.1 + -0.1x + x2 = 0 Move the constant term to the right: Add '8.1' to each side of the equation. -8.1 + -0.1x + 8.1 + x2 = 0 + 8.1 Reorder the terms: -8.1 + 8.1 + -0.1x + x2 = 0 + 8.1 Combine like terms: -8.1 + 8.1 = 0.0 0.0 + -0.1x + x2 = 0 + 8.1 -0.1x + x2 = 0 + 8.1 Combine like terms: 0 + 8.1 = 8.1 -0.1x + x2 = 8.1 The x term is -0.1x. Take half its coefficient (-0.05). Square it (0.0025) and add it to both sides. Add '0.0025' to each side of the equation. -0.1x + 0.0025 + x2 = 8.1 + 0.0025 Reorder the terms: 0.0025 + -0.1x + x2 = 8.1 + 0.0025 Combine like terms: 8.1 + 0.0025 = 8.1025 0.0025 + -0.1x + x2 = 8.1025 Factor a perfect square on the left side: (x + -0.05)(x + -0.05) = 8.1025 Calculate the square root of the right side: 2.846489065 Break this problem into two subproblems by setting (x + -0.05) equal to 2.846489065 and -2.846489065.Subproblem 1
x + -0.05 = 2.846489065 Simplifying x + -0.05 = 2.846489065 Reorder the terms: -0.05 + x = 2.846489065 Solving -0.05 + x = 2.846489065 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.05' to each side of the equation. -0.05 + 0.05 + x = 2.846489065 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + x = 2.846489065 + 0.05 x = 2.846489065 + 0.05 Combine like terms: 2.846489065 + 0.05 = 2.896489065 x = 2.896489065 Simplifying x = 2.896489065Subproblem 2
x + -0.05 = -2.846489065 Simplifying x + -0.05 = -2.846489065 Reorder the terms: -0.05 + x = -2.846489065 Solving -0.05 + x = -2.846489065 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.05' to each side of the equation. -0.05 + 0.05 + x = -2.846489065 + 0.05 Combine like terms: -0.05 + 0.05 = 0.00 0.00 + x = -2.846489065 + 0.05 x = -2.846489065 + 0.05 Combine like terms: -2.846489065 + 0.05 = -2.796489065 x = -2.796489065 Simplifying x = -2.796489065Solution
