Simplifying 0 = 0.5(x2 + x + -18) Reorder the terms: 0 = 0.5(-18 + x + x2) 0 = (-18 * 0.5 + x * 0.5 + x2 * 0.5) 0 = (-9 + 0.5x + 0.5x2) Solving 0 = -9 + 0.5x + 0.5x2 Solving for variable 'x'. Combine like terms: 0 + 9 = 9 9 + -0.5x + -0.5x2 = -9 + 0.5x + 0.5x2 + 9 + -0.5x + -0.5x2 Reorder the terms: 9 + -0.5x + -0.5x2 = -9 + 9 + 0.5x + -0.5x + 0.5x2 + -0.5x2 Combine like terms: -9 + 9 = 0 9 + -0.5x + -0.5x2 = 0 + 0.5x + -0.5x + 0.5x2 + -0.5x2 9 + -0.5x + -0.5x2 = 0.5x + -0.5x + 0.5x2 + -0.5x2 Combine like terms: 0.5x + -0.5x = 0.0 9 + -0.5x + -0.5x2 = 0.0 + 0.5x2 + -0.5x2 9 + -0.5x + -0.5x2 = 0.5x2 + -0.5x2 Combine like terms: 0.5x2 + -0.5x2 = 0.0 9 + -0.5x + -0.5x2 = 0.0 Begin completing the square. Divide all terms by -0.5 the coefficient of the squared term: Divide each side by '-0.5'. -18 + x + x2 = 0 Move the constant term to the right: Add '18' to each side of the equation. -18 + x + 18 + x2 = 0 + 18 Reorder the terms: -18 + 18 + x + x2 = 0 + 18 Combine like terms: -18 + 18 = 0 0 + x + x2 = 0 + 18 x + x2 = 0 + 18 Combine like terms: 0 + 18 = 18 x + x2 = 18 The x term is x. Take half its coefficient (0.5). Square it (0.25) and add it to both sides. Add '0.25' to each side of the equation. + 0.25 + x2 = 18 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 18 + 0.25 Combine like terms: 18 + 0.25 = 18.25 1.25 + x2 = 18.25 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 18.25 Calculate the square root of the right side: 4.272001873 Break this problem into two subproblems by setting (x + 0.5) equal to 4.272001873 and -4.272001873.Subproblem 1
x + 0.5 = 4.272001873 Simplifying x + 0.5 = 4.272001873 Reorder the terms: 0.5 + x = 4.272001873 Solving 0.5 + x = 4.272001873 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = 4.272001873 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 4.272001873 + -0.5 x = 4.272001873 + -0.5 Combine like terms: 4.272001873 + -0.5 = 3.772001873 x = 3.772001873 Simplifying x = 3.772001873Subproblem 2
x + 0.5 = -4.272001873 Simplifying x + 0.5 = -4.272001873 Reorder the terms: 0.5 + x = -4.272001873 Solving 0.5 + x = -4.272001873 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + x = -4.272001873 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -4.272001873 + -0.5 x = -4.272001873 + -0.5 Combine like terms: -4.272001873 + -0.5 = -4.772001873 x = -4.772001873 Simplifying x = -4.772001873Solution
The solution to the problem is based on the solutions from the subproblems. x = {3.772001873, -4.772001873}
