Simplifying x(2x + -5) = 196 Reorder the terms: x(-5 + 2x) = 196 (-5 * x + 2x * x) = 196 (-5x + 2x2) = 196 Solving -5x + 2x2 = 196 Solving for variable 'x'. Reorder the terms: -196 + -5x + 2x2 = 196 + -196 Combine like terms: 196 + -196 = 0 -196 + -5x + 2x2 = 0 Begin completing the square. Divide all terms by 2 the coefficient of the squared term: Divide each side by '2'. -98 + -2.5x + x2 = 0 Move the constant term to the right: Add '98' to each side of the equation. -98 + -2.5x + 98 + x2 = 0 + 98 Reorder the terms: -98 + 98 + -2.5x + x2 = 0 + 98 Combine like terms: -98 + 98 = 0 0 + -2.5x + x2 = 0 + 98 -2.5x + x2 = 0 + 98 Combine like terms: 0 + 98 = 98 -2.5x + x2 = 98 The x term is -2.5x. Take half its coefficient (-1.25). Square it (1.5625) and add it to both sides. Add '1.5625' to each side of the equation. -2.5x + 1.5625 + x2 = 98 + 1.5625 Reorder the terms: 1.5625 + -2.5x + x2 = 98 + 1.5625 Combine like terms: 98 + 1.5625 = 99.5625 1.5625 + -2.5x + x2 = 99.5625 Factor a perfect square on the left side: (x + -1.25)(x + -1.25) = 99.5625 Calculate the square root of the right side: 9.978101022 Break this problem into two subproblems by setting (x + -1.25) equal to 9.978101022 and -9.978101022.Subproblem 1
x + -1.25 = 9.978101022 Simplifying x + -1.25 = 9.978101022 Reorder the terms: -1.25 + x = 9.978101022 Solving -1.25 + x = 9.978101022 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = 9.978101022 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = 9.978101022 + 1.25 x = 9.978101022 + 1.25 Combine like terms: 9.978101022 + 1.25 = 11.228101022 x = 11.228101022 Simplifying x = 11.228101022Subproblem 2
x + -1.25 = -9.978101022 Simplifying x + -1.25 = -9.978101022 Reorder the terms: -1.25 + x = -9.978101022 Solving -1.25 + x = -9.978101022 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '1.25' to each side of the equation. -1.25 + 1.25 + x = -9.978101022 + 1.25 Combine like terms: -1.25 + 1.25 = 0.00 0.00 + x = -9.978101022 + 1.25 x = -9.978101022 + 1.25 Combine like terms: -9.978101022 + 1.25 = -8.728101022 x = -8.728101022 Simplifying x = -8.728101022Solution
The solution to the problem is based on the solutions from the subproblems. x = {11.228101022, -8.728101022}
