Simplifying 65 = 0.04x2 + -3x + 104 Reorder the terms: 65 = 104 + -3x + 0.04x2 Solving 65 = 104 + -3x + 0.04x2 Solving for variable 'x'. Combine like terms: 65 + -104 = -39 -39 + 3x + -0.04x2 = 104 + -3x + 0.04x2 + -104 + 3x + -0.04x2 Reorder the terms: -39 + 3x + -0.04x2 = 104 + -104 + -3x + 3x + 0.04x2 + -0.04x2 Combine like terms: 104 + -104 = 0 -39 + 3x + -0.04x2 = 0 + -3x + 3x + 0.04x2 + -0.04x2 -39 + 3x + -0.04x2 = -3x + 3x + 0.04x2 + -0.04x2 Combine like terms: -3x + 3x = 0 -39 + 3x + -0.04x2 = 0 + 0.04x2 + -0.04x2 -39 + 3x + -0.04x2 = 0.04x2 + -0.04x2 Combine like terms: 0.04x2 + -0.04x2 = 0.00 -39 + 3x + -0.04x2 = 0.00 Begin completing the square. Divide all terms by -0.04 the coefficient of the squared term: Divide each side by '-0.04'. 975 + -75x + x2 = 0 Move the constant term to the right: Add '-975' to each side of the equation. 975 + -75x + -975 + x2 = 0 + -975 Reorder the terms: 975 + -975 + -75x + x2 = 0 + -975 Combine like terms: 975 + -975 = 0 0 + -75x + x2 = 0 + -975 -75x + x2 = 0 + -975 Combine like terms: 0 + -975 = -975 -75x + x2 = -975 The x term is -75x. Take half its coefficient (-37.5). Square it (1406.25) and add it to both sides. Add '1406.25' to each side of the equation. -75x + 1406.25 + x2 = -975 + 1406.25 Reorder the terms: 1406.25 + -75x + x2 = -975 + 1406.25 Combine like terms: -975 + 1406.25 = 431.25 1406.25 + -75x + x2 = 431.25 Factor a perfect square on the left side: (x + -37.5)(x + -37.5) = 431.25 Calculate the square root of the right side: 20.766559657 Break this problem into two subproblems by setting (x + -37.5) equal to 20.766559657 and -20.766559657.Subproblem 1
x + -37.5 = 20.766559657 Simplifying x + -37.5 = 20.766559657 Reorder the terms: -37.5 + x = 20.766559657 Solving -37.5 + x = 20.766559657 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '37.5' to each side of the equation. -37.5 + 37.5 + x = 20.766559657 + 37.5 Combine like terms: -37.5 + 37.5 = 0.0 0.0 + x = 20.766559657 + 37.5 x = 20.766559657 + 37.5 Combine like terms: 20.766559657 + 37.5 = 58.266559657 x = 58.266559657 Simplifying x = 58.266559657Subproblem 2
