Simplifying 0.0000036 + -1x = x2 Solving 0.0000036 + -1x = x2 Solving for variable 'x'. Combine like terms: x2 + -1x2 = 0 0.0000036 + -1x + -1x2 = 0 Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. -0.0000036 + x + x2 = 0 Move the constant term to the right: Add '0.0000036' to each side of the equation. -0.0000036 + x + 0.0000036 + x2 = 0 + 0.0000036 Reorder the terms: -0.0000036 + 0.0000036 + x + x2 = 0 + 0.0000036 Combine like terms: -0.0000036 + 0.0000036 = 0.0000000 0.0000000 + x + x2 = 0 + 0.0000036 x + x2 = 0 + 0.0000036 Combine like terms: 0 + 0.0000036 = 0.0000036 x + x2 = 0.0000036 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 = 0.0000036 + 0.25 Combine like terms: + 0.25 = 1.25 1.25 + x2 = 0.0000036 + 0.25 Combine like terms: 0.0000036 + 0.25 = 0.2500036 1.25 + x2 = 0.2500036 Factor a perfect square on the left side: (x + 0.5)(x + 0.5) = 0.2500036 Calculate the square root of the right side: 0.5000036 Break this problem into two subproblems by setting (x + 0.5) equal to 0.5000036 and -0.5000036.Subproblem 1
x + 0.5 = 0.5000036 Simplifying x + 0.5 = 0.5000036 Reorder the terms: 0.5 + x = 0.5000036 Solving 0.5 + x = 0.5000036 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 = 0.5000036 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = 0.5000036 + -0.5 x = 0.5000036 + -0.5 Combine like terms: 0.5000036 + -0.5 = 0.0000036 x = 0.0000036 Simplifying x = 0.0000036Subproblem 2
x + 0.5 = -0.5000036 Simplifying x + 0.5 = -0.5000036 Reorder the terms: 0.5 + x = -0.5000036 Solving 0.5 + x = -0.5000036 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 = -0.5000036 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + x = -0.5000036 + -0.5 x = -0.5000036 + -0.5 Combine like terms: -0.5000036 + -0.5 = -1.0000036 x = -1.0000036 Simplifying x = -1.0000036Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.0000036, -1.0000036}
