Simplifying x2 + 20x + -2 = 0 Reorder the terms: -2 + 20x + x2 = 0 Solving -2 + 20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '2' to each side of the equation. -2 + 20x + 2 + x2 = 0 + 2 Reorder the terms: -2 + 2 + 20x + x2 = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 20x + x2 = 0 + 2 20x + x2 = 0 + 2 Combine like terms: 0 + 2 = 2 20x + x2 = 2 The x term is 20x. Take half its coefficient (10). Square it (100) and add it to both sides. Add '100' to each side of the equation. 20x + 100 + x2 = 2 + 100 Reorder the terms: 100 + 20x + x2 = 2 + 100 Combine like terms: 2 + 100 = 102 100 + 20x + x2 = 102 Factor a perfect square on the left side: (x + 10)(x + 10) = 102 Calculate the square root of the right side: 10.099504938 Break this problem into two subproblems by setting (x + 10) equal to 10.099504938 and -10.099504938.Subproblem 1
x + 10 = 10.099504938 Simplifying x + 10 = 10.099504938 Reorder the terms: 10 + x = 10.099504938 Solving 10 + x = 10.099504938 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = 10.099504938 + -10 Combine like terms: 10 + -10 = 0 0 + x = 10.099504938 + -10 x = 10.099504938 + -10 Combine like terms: 10.099504938 + -10 = 0.099504938 x = 0.099504938 Simplifying x = 0.099504938Subproblem 2
x + 10 = -10.099504938 Simplifying x + 10 = -10.099504938 Reorder the terms: 10 + x = -10.099504938 Solving 10 + x = -10.099504938 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-10' to each side of the equation. 10 + -10 + x = -10.099504938 + -10 Combine like terms: 10 + -10 = 0 0 + x = -10.099504938 + -10 x = -10.099504938 + -10 Combine like terms: -10.099504938 + -10 = -20.099504938 x = -20.099504938 Simplifying x = -20.099504938Solution
The solution to the problem is based on the solutions from the subproblems. x = {0.099504938, -20.099504938}
