Simplifying x2 + 0.1x = 0.00000002 Reorder the terms: 0.1x + x2 = 0.00000002 Solving 0.1x + x2 = 0.00000002 Solving for variable 'x'. Reorder the terms: -0.00000002 + 0.1x + x2 = 0.00000002 + -0.00000002 Combine like terms: 0.00000002 + -0.00000002 = 0.00000000 -0.00000002 + 0.1x + x2 = 0.00000000 Begin completing the square. Move the constant term to the right: Add '0.00000002' to each side of the equation. -0.00000002 + 0.1x + 0.00000002 + x2 = 0.00000000 + 0.00000002 Reorder the terms: -0.00000002 + 0.00000002 + 0.1x + x2 = 0.00000000 + 0.00000002 Combine like terms: -0.00000002 + 0.00000002 = 0.00000000 0.00000000 + 0.1x + x2 = 0.00000000 + 0.00000002 0.1x + x2 = 0.00000000 + 0.00000002 Combine like terms: 0.00000000 + 0.00000002 = 0.00000002 0.1x + x2 = 0.00000002 The x term is 0.1x. Take half its coefficient (0.05). Square it (0.0025) and add it to both sides. Add '0.0025' to each side of the equation. 0.1x + 0.0025 + x2 = 0.00000002 + 0.0025 Reorder the terms: 0.0025 + 0.1x + x2 = 0.00000002 + 0.0025 Combine like terms: 0.00000002 + 0.0025 = 0.00250002 0.0025 + 0.1x + x2 = 0.00250002 Factor a perfect square on the left side: (x + 0.05)(x + 0.05) = 0.00250002 Calculate the square root of the right side: 0.0500002 Break this problem into two subproblems by setting (x + 0.05) equal to 0.0500002 and -0.0500002.Subproblem 1
x + 0.05 = 0.0500002 Simplifying x + 0.05 = 0.0500002 Reorder the terms: 0.05 + x = 0.0500002 Solving 0.05 + x = 0.0500002 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.05' to each side of the equation. 0.05 + -0.05 + x = 0.0500002 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = 0.0500002 + -0.05 x = 0.0500002 + -0.05 Combine like terms: 0.0500002 + -0.05 = 0.0000002 x = 0.0000002 Simplifying x = 0.0000002Subproblem 2
x + 0.05 = -0.0500002 Simplifying x + 0.05 = -0.0500002 Reorder the terms: 0.05 + x = -0.0500002 Solving 0.05 + x = -0.0500002 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-0.05' to each side of the equation. 0.05 + -0.05 + x = -0.0500002 + -0.05 Combine like terms: 0.05 + -0.05 = 0.00 0.00 + x = -0.0500002 + -0.05 x = -0.0500002 + -0.05 Combine like terms: -0.0500002 + -0.05 = -0.1000002 x = -0.1000002 Simplifying x = -0.1000002Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.0000002, -0.1000002}
