Subproblem 1

Set the factor '(-1 + 10x + 500000x2)' equal to zero and attempt to solve: Simplifying -1 + 10x + 500000x2 = 0 Solving -1 + 10x + 500000x2 = 0 Begin completing the square. Divide all terms by 500000 the coefficient of the squared term: Divide each side by '500000'. -0.000002 + 0.00002x + x2 = 0.00000 Move the constant term to the right: Add '0.000002' to each side of the equation. -0.000002 + 0.00002x + 0.000002 + x2 = 0.00000 + 0.000002 Reorder the terms: -0.000002 + 0.000002 + 0.00002x + x2 = 0.00000 + 0.000002 Combine like terms: -0.000002 + 0.000002 = 0.000000 0.000000 + 0.00002x + x2 = 0.00000 + 0.000002 0.00002x + x2 = 0.00000 + 0.000002 Combine like terms: 0.00000 + 0.000002 = 0.000002 0.00002x + x2 = 0.000002 The x term is 0.00002x. Take half its coefficient (0.00001). Square it (0.0000000001) and add it to both sides. Add '0.0000000001' to each side of the equation. 0.00002x + 0.0000000001 + x2 = 0.000002 + 0.0000000001 Reorder the terms: 0.0000000001 + 0.00002x + x2 = 0.000002 + 0.0000000001 Combine like terms: 0.000002 + 0.0000000001 = 0.0000020001 0.0000000001 + 0.00002x + x2 = 0.0000020001 Factor a perfect square on the left side: (x + 0.00001)(x + 0.00001) = 0.0000020001 Calculate the square root of the right side: 0.001414249 Break this problem into two subproblems by setting (x + 0.00001) equal to 0.001414249 and -0.001414249.
