Simplifying 2x2 + 25x + 48 = 0 Reorder the terms: 48 + 25x + 2x2 = 0 Solving 48 + 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'. 24 + 12.5x + x2 = 0 Move the constant term to the right: Add '-24' to each side of the equation. 24 + 12.5x + -24 + x2 = 0 + -24 Reorder the terms: 24 + -24 + 12.5x + x2 = 0 + -24 Combine like terms: 24 + -24 = 0 0 + 12.5x + x2 = 0 + -24 12.5x + x2 = 0 + -24 Combine like terms: 0 + -24 = -24 12.5x + x2 = -24 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 = -24 + 39.0625 Reorder the terms: 39.0625 + 12.5x + x2 = -24 + 39.0625 Combine like terms: -24 + 39.0625 = 15.0625 39.0625 + 12.5x + x2 = 15.0625 Factor a perfect square on the left side: (x + 6.25)(x + 6.25) = 15.0625 Calculate the square root of the right side: 3.881043674 Break this problem into two subproblems by setting (x + 6.25) equal to 3.881043674 and -3.881043674.Subproblem 1
x + 6.25 = 3.881043674 Simplifying x + 6.25 = 3.881043674 Reorder the terms: 6.25 + x = 3.881043674 Solving 6.25 + x = 3.881043674 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 = 3.881043674 + -6.25 Combine like terms: 6.25 + -6.25 = 0.00 0.00 + x = 3.881043674 + -6.25 x = 3.881043674 + -6.25 Combine like terms: 3.881043674 + -6.25 = -2.368956326 x = -2.368956326 Simplifying x = -2.368956326Subproblem 2
x + 6.25 = -3.881043674 Simplifying x + 6.25 = -3.881043674 Reorder the terms: 6.25 + x = -3.881043674 Solving 6.25 + x = -3.881043674 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 = -3.881043674 + -6.25 Combine like terms: 6.25 + -6.25 = 0.00 0.00 + x = -3.881043674 + -6.25 x = -3.881043674 + -6.25 Combine like terms: -3.881043674 + -6.25 = -10.131043674 x = -10.131043674 Simplifying x = -10.131043674Solution
