Simplifying -0.02x2 + 0.9x + 40 = 0 Reorder the terms: 40 + 0.9x + -0.02x2 = 0 Solving 40 + 0.9x + -0.02x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -0.02 the coefficient of the squared term: Divide each side by '-0.02'. -2000 + -45x + x2 = 0 Move the constant term to the right: Add '2000' to each side of the equation. -2000 + -45x + 2000 + x2 = 0 + 2000 Reorder the terms: -2000 + 2000 + -45x + x2 = 0 + 2000 Combine like terms: -2000 + 2000 = 0 0 + -45x + x2 = 0 + 2000 -45x + x2 = 0 + 2000 Combine like terms: 0 + 2000 = 2000 -45x + x2 = 2000 The x term is -45x. Take half its coefficient (-22.5). Square it (506.25) and add it to both sides. Add '506.25' to each side of the equation. -45x + 506.25 + x2 = 2000 + 506.25 Reorder the terms: 506.25 + -45x + x2 = 2000 + 506.25 Combine like terms: 2000 + 506.25 = 2506.25 506.25 + -45x + x2 = 2506.25 Factor a perfect square on the left side: (x + -22.5)(x + -22.5) = 2506.25 Calculate the square root of the right side: 50.062460986 Break this problem into two subproblems by setting (x + -22.5) equal to 50.062460986 and -50.062460986.Subproblem 1
x + -22.5 = 50.062460986 Simplifying x + -22.5 = 50.062460986 Reorder the terms: -22.5 + x = 50.062460986 Solving -22.5 + x = 50.062460986 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '22.5' to each side of the equation. -22.5 + 22.5 + x = 50.062460986 + 22.5 Combine like terms: -22.5 + 22.5 = 0.0 0.0 + x = 50.062460986 + 22.5 x = 50.062460986 + 22.5 Combine like terms: 50.062460986 + 22.5 = 72.562460986 x = 72.562460986 Simplifying x = 72.562460986Subproblem 2
x + -22.5 = -50.062460986 Simplifying x + -22.5 = -50.062460986 Reorder the terms: -22.5 + x = -50.062460986 Solving -22.5 + x = -50.062460986 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '22.5' to each side of the equation. -22.5 + 22.5 + x = -50.062460986 + 22.5 Combine like terms: -22.5 + 22.5 = 0.0 0.0 + x = -50.062460986 + 22.5 x = -50.062460986 + 22.5 Combine like terms: -50.062460986 + 22.5 = -27.562460986 x = -27.562460986 Simplifying x = -27.562460986Solution
