Simplifying 0.1x2 + 8x + -50 = 0 Reorder the terms: -50 + 8x + 0.1x2 = 0 Solving -50 + 8x + 0.1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.1 the coefficient of the squared term: Divide each side by '0.1'. -500 + 80x + x2 = 0 Move the constant term to the right: Add '500' to each side of the equation. -500 + 80x + 500 + x2 = 0 + 500 Reorder the terms: -500 + 500 + 80x + x2 = 0 + 500 Combine like terms: -500 + 500 = 0 0 + 80x + x2 = 0 + 500 80x + x2 = 0 + 500 Combine like terms: 0 + 500 = 500 80x + x2 = 500 The x term is 80x. Take half its coefficient (40). Square it (1600) and add it to both sides. Add '1600' to each side of the equation. 80x + 1600 + x2 = 500 + 1600 Reorder the terms: 1600 + 80x + x2 = 500 + 1600 Combine like terms: 500 + 1600 = 2100 1600 + 80x + x2 = 2100 Factor a perfect square on the left side: (x + 40)(x + 40) = 2100 Calculate the square root of the right side: 45.82575695 Break this problem into two subproblems by setting (x + 40) equal to 45.82575695 and -45.82575695.Subproblem 1
x + 40 = 45.82575695 Simplifying x + 40 = 45.82575695 Reorder the terms: 40 + x = 45.82575695 Solving 40 + x = 45.82575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-40' to each side of the equation. 40 + -40 + x = 45.82575695 + -40 Combine like terms: 40 + -40 = 0 0 + x = 45.82575695 + -40 x = 45.82575695 + -40 Combine like terms: 45.82575695 + -40 = 5.82575695 x = 5.82575695 Simplifying x = 5.82575695Subproblem 2
x + 40 = -45.82575695 Simplifying x + 40 = -45.82575695 Reorder the terms: 40 + x = -45.82575695 Solving 40 + x = -45.82575695 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-40' to each side of the equation. 40 + -40 + x = -45.82575695 + -40 Combine like terms: 40 + -40 = 0 0 + x = -45.82575695 + -40 x = -45.82575695 + -40 Combine like terms: -45.82575695 + -40 = -85.82575695 x = -85.82575695 Simplifying x = -85.82575695Solution
