Simplifying x2 + -20x + 35 = 0 Reorder the terms: 35 + -20x + x2 = 0 Solving 35 + -20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-35' to each side of the equation. 35 + -20x + -35 + x2 = 0 + -35 Reorder the terms: 35 + -35 + -20x + x2 = 0 + -35 Combine like terms: 35 + -35 = 0 0 + -20x + x2 = 0 + -35 -20x + x2 = 0 + -35 Combine like terms: 0 + -35 = -35 -20x + x2 = -35 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 = -35 + 100 Reorder the terms: 100 + -20x + x2 = -35 + 100 Combine like terms: -35 + 100 = 65 100 + -20x + x2 = 65 Factor a perfect square on the left side: (x + -10)(x + -10) = 65 Calculate the square root of the right side: 8.062257748 Break this problem into two subproblems by setting (x + -10) equal to 8.062257748 and -8.062257748.Subproblem 1
x + -10 = 8.062257748 Simplifying x + -10 = 8.062257748 Reorder the terms: -10 + x = 8.062257748 Solving -10 + x = 8.062257748 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 = 8.062257748 + 10 Combine like terms: -10 + 10 = 0 0 + x = 8.062257748 + 10 x = 8.062257748 + 10 Combine like terms: 8.062257748 + 10 = 18.062257748 x = 18.062257748 Simplifying x = 18.062257748Subproblem 2
x + -10 = -8.062257748 Simplifying x + -10 = -8.062257748 Reorder the terms: -10 + x = -8.062257748 Solving -10 + x = -8.062257748 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 = -8.062257748 + 10 Combine like terms: -10 + 10 = 0 0 + x = -8.062257748 + 10 x = -8.062257748 + 10 Combine like terms: -8.062257748 + 10 = 1.937742252 x = 1.937742252 Simplifying x = 1.937742252Solution
The solution to the problem is based on the solutions from the subproblems. x = {18.062257748, 1.937742252}
