Simplifying x2 + -20x + 83 = 0 Reorder the terms: 83 + -20x + x2 = 0 Solving 83 + -20x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-83' to each side of the equation. 83 + -20x + -83 + x2 = 0 + -83 Reorder the terms: 83 + -83 + -20x + x2 = 0 + -83 Combine like terms: 83 + -83 = 0 0 + -20x + x2 = 0 + -83 -20x + x2 = 0 + -83 Combine like terms: 0 + -83 = -83 -20x + x2 = -83 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 = -83 + 100 Reorder the terms: 100 + -20x + x2 = -83 + 100 Combine like terms: -83 + 100 = 17 100 + -20x + x2 = 17 Factor a perfect square on the left side: (x + -10)(x + -10) = 17 Calculate the square root of the right side: 4.123105626 Break this problem into two subproblems by setting (x + -10) equal to 4.123105626 and -4.123105626.Subproblem 1
x + -10 = 4.123105626 Simplifying x + -10 = 4.123105626 Reorder the terms: -10 + x = 4.123105626 Solving -10 + x = 4.123105626 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 = 4.123105626 + 10 Combine like terms: -10 + 10 = 0 0 + x = 4.123105626 + 10 x = 4.123105626 + 10 Combine like terms: 4.123105626 + 10 = 14.123105626 x = 14.123105626 Simplifying x = 14.123105626Subproblem 2
x + -10 = -4.123105626 Simplifying x + -10 = -4.123105626 Reorder the terms: -10 + x = -4.123105626 Solving -10 + x = -4.123105626 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 = -4.123105626 + 10 Combine like terms: -10 + 10 = 0 0 + x = -4.123105626 + 10 x = -4.123105626 + 10 Combine like terms: -4.123105626 + 10 = 5.876894374 x = 5.876894374 Simplifying x = 5.876894374Solution
The solution to the problem is based on the solutions from the subproblems. x = {14.123105626, 5.876894374}
