Simplifying -0.01x2 + -2x + -40 = 0 Reorder the terms: -40 + -2x + -0.01x2 = 0 Solving -40 + -2x + -0.01x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.01 the coefficient of the squared term: Divide each side by '-0.01'. 4000 + 200x + x2 = 0 Move the constant term to the right: Add '-4000' to each side of the equation. 4000 + 200x + -4000 + x2 = 0 + -4000 Reorder the terms: 4000 + -4000 + 200x + x2 = 0 + -4000 Combine like terms: 4000 + -4000 = 0 0 + 200x + x2 = 0 + -4000 200x + x2 = 0 + -4000 Combine like terms: 0 + -4000 = -4000 200x + x2 = -4000 The x term is 200x. Take half its coefficient (100). Square it (10000) and add it to both sides. Add '10000' to each side of the equation. 200x + 10000 + x2 = -4000 + 10000 Reorder the terms: 10000 + 200x + x2 = -4000 + 10000 Combine like terms: -4000 + 10000 = 6000 10000 + 200x + x2 = 6000 Factor a perfect square on the left side: (x + 100)(x + 100) = 6000 Calculate the square root of the right side: 77.459666924 Break this problem into two subproblems by setting (x + 100) equal to 77.459666924 and -77.459666924.Subproblem 1
x + 100 = 77.459666924 Simplifying x + 100 = 77.459666924 Reorder the terms: 100 + x = 77.459666924 Solving 100 + x = 77.459666924 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-100' to each side of the equation. 100 + -100 + x = 77.459666924 + -100 Combine like terms: 100 + -100 = 0 0 + x = 77.459666924 + -100 x = 77.459666924 + -100 Combine like terms: 77.459666924 + -100 = -22.540333076 x = -22.540333076 Simplifying x = -22.540333076Subproblem 2
x + 100 = -77.459666924 Simplifying x + 100 = -77.459666924 Reorder the terms: 100 + x = -77.459666924 Solving 100 + x = -77.459666924 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-100' to each side of the equation. 100 + -100 + x = -77.459666924 + -100 Combine like terms: 100 + -100 = 0 0 + x = -77.459666924 + -100 x = -77.459666924 + -100 Combine like terms: -77.459666924 + -100 = -177.459666924 x = -177.459666924 Simplifying x = -177.459666924Solution
The solution to the problem is based on the solutions from the subproblems. x = {-22.540333076, -177.459666924}
