Simplifying X2 + -20X + -20 = 0 Reorder the terms: -20 + -20X + X2 = 0 Solving -20 + -20X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '20' to each side of the equation. -20 + -20X + 20 + X2 = 0 + 20 Reorder the terms: -20 + 20 + -20X + X2 = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -20X + X2 = 0 + 20 -20X + X2 = 0 + 20 Combine like terms: 0 + 20 = 20 -20X + X2 = 20 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 = 20 + 100 Reorder the terms: 100 + -20X + X2 = 20 + 100 Combine like terms: 20 + 100 = 120 100 + -20X + X2 = 120 Factor a perfect square on the left side: (X + -10)(X + -10) = 120 Calculate the square root of the right side: 10.95445115 Break this problem into two subproblems by setting (X + -10) equal to 10.95445115 and -10.95445115.Subproblem 1
X + -10 = 10.95445115 Simplifying X + -10 = 10.95445115 Reorder the terms: -10 + X = 10.95445115 Solving -10 + X = 10.95445115 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 = 10.95445115 + 10 Combine like terms: -10 + 10 = 0 0 + X = 10.95445115 + 10 X = 10.95445115 + 10 Combine like terms: 10.95445115 + 10 = 20.95445115 X = 20.95445115 Simplifying X = 20.95445115Subproblem 2
X + -10 = -10.95445115 Simplifying X + -10 = -10.95445115 Reorder the terms: -10 + X = -10.95445115 Solving -10 + X = -10.95445115 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 = -10.95445115 + 10 Combine like terms: -10 + 10 = 0 0 + X = -10.95445115 + 10 X = -10.95445115 + 10 Combine like terms: -10.95445115 + 10 = -0.95445115 X = -0.95445115 Simplifying X = -0.95445115Solution
The solution to the problem is based on the solutions from the subproblems. X = {20.95445115, -0.95445115}
