Simplifying 5 * 8x + x2 = 85 Multiply 5 * 8 40x + x2 = 85 Solving 40x + x2 = 85 Solving for variable 'x'. Reorder the terms: -85 + 40x + x2 = 85 + -85 Combine like terms: 85 + -85 = 0 -85 + 40x + x2 = 0 Begin completing the square. Move the constant term to the right: Add '85' to each side of the equation. -85 + 40x + 85 + x2 = 0 + 85 Reorder the terms: -85 + 85 + 40x + x2 = 0 + 85 Combine like terms: -85 + 85 = 0 0 + 40x + x2 = 0 + 85 40x + x2 = 0 + 85 Combine like terms: 0 + 85 = 85 40x + x2 = 85 The x term is 40x. Take half its coefficient (20). Square it (400) and add it to both sides. Add '400' to each side of the equation. 40x + 400 + x2 = 85 + 400 Reorder the terms: 400 + 40x + x2 = 85 + 400 Combine like terms: 85 + 400 = 485 400 + 40x + x2 = 485 Factor a perfect square on the left side: (x + 20)(x + 20) = 485 Calculate the square root of the right side: 22.022715546 Break this problem into two subproblems by setting (x + 20) equal to 22.022715546 and -22.022715546.Subproblem 1
x + 20 = 22.022715546 Simplifying x + 20 = 22.022715546 Reorder the terms: 20 + x = 22.022715546 Solving 20 + x = 22.022715546 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = 22.022715546 + -20 Combine like terms: 20 + -20 = 0 0 + x = 22.022715546 + -20 x = 22.022715546 + -20 Combine like terms: 22.022715546 + -20 = 2.022715546 x = 2.022715546 Simplifying x = 2.022715546Subproblem 2
x + 20 = -22.022715546 Simplifying x + 20 = -22.022715546 Reorder the terms: 20 + x = -22.022715546 Solving 20 + x = -22.022715546 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + x = -22.022715546 + -20 Combine like terms: 20 + -20 = 0 0 + x = -22.022715546 + -20 x = -22.022715546 + -20 Combine like terms: -22.022715546 + -20 = -42.022715546 x = -42.022715546 Simplifying x = -42.022715546Solution
