Simplifying 0.16x2 + 0.16x + -0.26 = 0 Reorder the terms: -0.26 + 0.16x + 0.16x2 = 0 Solving -0.26 + 0.16x + 0.16x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by 0.16 the coefficient of the squared term: Divide each side by '0.16'. -1.625 + x + x2 = 0 Move the constant term to the right: Add '1.625' to each side of the equation. -1.625 + x + 1.625 + x2 = 0 + 1.625 Reorder the terms: -1.625 + 1.625 + x + x2 = 0 + 1.625 Combine like terms: -1.625 + 1.625 = 0.000 0.000 + x + x2 = 0 + 1.625 x + x2 = 0 + 1.625 Combine like terms: 0 + 1.625 = 1.625 x + x2 = 1.625 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 = 1.625 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 1.625 + 0.25 Combine like terms: 1.625 + 0.25 = 1.875 1.25 + x2 = 1.875 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 1.875 Calculate the square root of the right side: 1.369306394 Break this problem into two subproblems by setting (x + 0.5) equal to 1.369306394 and -1.369306394.Subproblem 1
x + 0.5 = 1.369306394 Simplifying x + 0.5 = 1.369306394 Reorder the terms: 0.5 + x = 1.369306394 Solving 0.5 + x = 1.369306394 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 = 1.369306394 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 1.369306394 + -0.5 x = 1.369306394 + -0.5 Combine like terms: 1.369306394 + -0.5 = 0.869306394 x = 0.869306394 Simplifying x = 0.869306394Subproblem 2
x + 0.5 = -1.369306394 Simplifying x + 0.5 = -1.369306394 Reorder the terms: 0.5 + x = -1.369306394 Solving 0.5 + x = -1.369306394 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 = -1.369306394 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -1.369306394 + -0.5 x = -1.369306394 + -0.5 Combine like terms: -1.369306394 + -0.5 = -1.869306394 x = -1.869306394 Simplifying x = -1.869306394Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.869306394, -1.869306394}
