Simplifying 20x2 + -1x + -80 = 0 Reorder the terms: -80 + -1x + 20x2 = 0 Solving -80 + -1x + 20x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 20 the coefficient of the squared term: Divide each side by '20'. -4 + -0.05x + x2 = 0 Move the constant term to the right: Add '4' to each side of the equation. -4 + -0.05x + 4 + x2 = 0 + 4 Reorder the terms: -4 + 4 + -0.05x + x2 = 0 + 4 Combine like terms: -4 + 4 = 0 0 + -0.05x + x2 = 0 + 4 -0.05x + x2 = 0 + 4 Combine like terms: 0 + 4 = 4 -0.05x + x2 = 4 The x term is -0.05x. Take half its coefficient (-0.025). Square it (0.000625) and add it to both sides. Add '0.000625' to each side of the equation. -0.05x + 0.000625 + x2 = 4 + 0.000625 Reorder the terms: 0.000625 + -0.05x + x2 = 4 + 0.000625 Combine like terms: 4 + 0.000625 = 4.000625 0.000625 + -0.05x + x2 = 4.000625 Factor a perfect square on the left side: (x + -0.025)(x + -0.025) = 4.000625 Calculate the square root of the right side: 2.000156244 Break this problem into two subproblems by setting (x + -0.025) equal to 2.000156244 and -2.000156244.Subproblem 1
x + -0.025 = 2.000156244 Simplifying x + -0.025 = 2.000156244 Reorder the terms: -0.025 + x = 2.000156244 Solving -0.025 + x = 2.000156244 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.025' to each side of the equation. -0.025 + 0.025 + x = 2.000156244 + 0.025 Combine like terms: -0.025 + 0.025 = 0.000 0.000 + x = 2.000156244 + 0.025 x = 2.000156244 + 0.025 Combine like terms: 2.000156244 + 0.025 = 2.025156244 x = 2.025156244 Simplifying x = 2.025156244Subproblem 2
x + -0.025 = -2.000156244 Simplifying x + -0.025 = -2.000156244 Reorder the terms: -0.025 + x = -2.000156244 Solving -0.025 + x = -2.000156244 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '0.025' to each side of the equation. -0.025 + 0.025 + x = -2.000156244 + 0.025 Combine like terms: -0.025 + 0.025 = 0.000 0.000 + x = -2.000156244 + 0.025 x = -2.000156244 + 0.025 Combine like terms: -2.000156244 + 0.025 = -1.975156244 x = -1.975156244 Simplifying x = -1.975156244Solution
