Simplifying 0 = 50x2 + -50x + 1 Reorder the terms: 0 = 1 + -50x + 50x2 Solving 0 = 1 + -50x + 50x2 Solving for variable 'x'. Combine like terms: 0 + -1 = -1 -1 + 50x + -50x2 = 1 + -50x + 50x2 + -1 + 50x + -50x2 Reorder the terms: -1 + 50x + -50x2 = 1 + -1 + -50x + 50x + 50x2 + -50x2 Combine like terms: 1 + -1 = 0 -1 + 50x + -50x2 = 0 + -50x + 50x + 50x2 + -50x2 -1 + 50x + -50x2 = -50x + 50x + 50x2 + -50x2 Combine like terms: -50x + 50x = 0 -1 + 50x + -50x2 = 0 + 50x2 + -50x2 -1 + 50x + -50x2 = 50x2 + -50x2 Combine like terms: 50x2 + -50x2 = 0 -1 + 50x + -50x2 = 0 Begin completing the square. Divide all terms by -50 the coefficient of the squared term: Divide each side by '-50'. 0.02 + -1x + x2 = 0 Move the constant term to the right: Add '-0.02' to each side of the equation. 0.02 + -1x + -0.02 + x2 = 0 + -0.02 Reorder the terms: 0.02 + -0.02 + -1x + x2 = 0 + -0.02 Combine like terms: 0.02 + -0.02 = 0.00 0.00 + -1x + x2 = 0 + -0.02 -1x + x2 = 0 + -0.02 Combine like terms: 0 + -0.02 = -0.02 -1x + x2 = -0.02 The x term is -1x. 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. -1x + 0.25 + x2 = -0.02 + 0.25 Reorder the terms: 0.25 + -1x + x2 = -0.02 + 0.25 Combine like terms: -0.02 + 0.25 = 0.23 0.25 + -1x + x2 = 0.23 Factor a perfect square on the left side: (x + -0.5)(x + -0.5) = 0.23 Calculate the square root of the right side: 0.479583152 Break this problem into two subproblems by setting (x + -0.5) equal to 0.479583152 and -0.479583152.Subproblem 1
x + -0.5 = 0.479583152 Simplifying x + -0.5 = 0.479583152 Reorder the terms: -0.5 + x = 0.479583152 Solving -0.5 + x = 0.479583152 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 = 0.479583152 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = 0.479583152 + 0.5 x = 0.479583152 + 0.5 Combine like terms: 0.479583152 + 0.5 = 0.979583152 x = 0.979583152 Simplifying x = 0.979583152Subproblem 2
x + -0.5 = -0.479583152 Simplifying x + -0.5 = -0.479583152 Reorder the terms: -0.5 + x = -0.479583152 Solving -0.5 + x = -0.479583152 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 = -0.479583152 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + x = -0.479583152 + 0.5 x = -0.479583152 + 0.5 Combine like terms: -0.479583152 + 0.5 = 0.020416848 x = 0.020416848 Simplifying x = 0.020416848Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.979583152, 0.020416848}
