Simplifying 2x2 + 25x + -20 = 0 Reorder the terms: -20 + 25x + 2x2 = 0 Solving -20 + 25x + 2x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -10 + 12.5x + x2 = 0 Move the constant term to the right: Add '10' to each side of the equation. -10 + 12.5x + 10 + x2 = 0 + 10 Reorder the terms: -10 + 10 + 12.5x + x2 = 0 + 10 Combine like terms: -10 + 10 = 0 0 + 12.5x + x2 = 0 + 10 12.5x + x2 = 0 + 10 Combine like terms: 0 + 10 = 10 12.5x + x2 = 10 The x term is 12.5x. Take half its coefficient (6.25). Square it (39.0625) and add it to both sides. Add '39.0625' to each side of the equation. 12.5x + 39.0625 + x2 = 10 + 39.0625 Reorder the terms: 39.0625 + 12.5x + x2 = 10 + 39.0625 Combine like terms: 10 + 39.0625 = 49.0625 39.0625 + 12.5x + x2 = 49.0625 Factor a perfect square on the left side: (x + 6.25)(x + 6.25) = 49.0625 Calculate the square root of the right side: 7.004462863 Break this problem into two subproblems by setting (x + 6.25) equal to 7.004462863 and -7.004462863.Subproblem 1
x + 6.25 = 7.004462863 Simplifying x + 6.25 = 7.004462863 Reorder the terms: 6.25 + x = 7.004462863 Solving 6.25 + x = 7.004462863 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.25' to each side of the equation. 6.25 + -6.25 + x = 7.004462863 + -6.25 Combine like terms: 6.25 + -6.25 = 0.00 0.00 + x = 7.004462863 + -6.25 x = 7.004462863 + -6.25 Combine like terms: 7.004462863 + -6.25 = 0.754462863 x = 0.754462863 Simplifying x = 0.754462863Subproblem 2
x + 6.25 = -7.004462863 Simplifying x + 6.25 = -7.004462863 Reorder the terms: 6.25 + x = -7.004462863 Solving 6.25 + x = -7.004462863 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6.25' to each side of the equation. 6.25 + -6.25 + x = -7.004462863 + -6.25 Combine like terms: 6.25 + -6.25 = 0.00 0.00 + x = -7.004462863 + -6.25 x = -7.004462863 + -6.25 Combine like terms: -7.004462863 + -6.25 = -13.254462863 x = -13.254462863 Simplifying x = -13.254462863Solution
