Simplifying 8x2 + 18x + -25 = 0 Reorder the terms: -25 + 18x + 8x2 = 0 Solving -25 + 18x + 8x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 8 the coefficient of the squared term: Divide each side by '8'. -3.125 + 2.25x + x2 = 0 Move the constant term to the right: Add '3.125' to each side of the equation. -3.125 + 2.25x + 3.125 + x2 = 0 + 3.125 Reorder the terms: -3.125 + 3.125 + 2.25x + x2 = 0 + 3.125 Combine like terms: -3.125 + 3.125 = 0.000 0.000 + 2.25x + x2 = 0 + 3.125 2.25x + x2 = 0 + 3.125 Combine like terms: 0 + 3.125 = 3.125 2.25x + x2 = 3.125 The x term is 2.25x. Take half its coefficient (1.125). Square it (1.265625) and add it to both sides. Add '1.265625' to each side of the equation. 2.25x + 1.265625 + x2 = 3.125 + 1.265625 Reorder the terms: 1.265625 + 2.25x + x2 = 3.125 + 1.265625 Combine like terms: 3.125 + 1.265625 = 4.390625 1.265625 + 2.25x + x2 = 4.390625 Factor a perfect square on the left side: (x + 1.125)(x + 1.125) = 4.390625 Calculate the square root of the right side: 2.095381827 Break this problem into two subproblems by setting (x + 1.125) equal to 2.095381827 and -2.095381827.Subproblem 1
x + 1.125 = 2.095381827 Simplifying x + 1.125 = 2.095381827 Reorder the terms: 1.125 + x = 2.095381827 Solving 1.125 + x = 2.095381827 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = 2.095381827 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = 2.095381827 + -1.125 x = 2.095381827 + -1.125 Combine like terms: 2.095381827 + -1.125 = 0.970381827 x = 0.970381827 Simplifying x = 0.970381827Subproblem 2
x + 1.125 = -2.095381827 Simplifying x + 1.125 = -2.095381827 Reorder the terms: 1.125 + x = -2.095381827 Solving 1.125 + x = -2.095381827 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1.125' to each side of the equation. 1.125 + -1.125 + x = -2.095381827 + -1.125 Combine like terms: 1.125 + -1.125 = 0.000 0.000 + x = -2.095381827 + -1.125 x = -2.095381827 + -1.125 Combine like terms: -2.095381827 + -1.125 = -3.220381827 x = -3.220381827 Simplifying x = -3.220381827Solution
