Simplifying X2 + 40X + -5 = 0 Reorder the terms: -5 + 40X + X2 = 0 Solving -5 + 40X + X2 = 0 Solving for variable 'X'. Begin completing the square. Move the constant term to the right: Add '5' to each side of the equation. -5 + 40X + 5 + X2 = 0 + 5 Reorder the terms: -5 + 5 + 40X + X2 = 0 + 5 Combine like terms: -5 + 5 = 0 0 + 40X + X2 = 0 + 5 40X + X2 = 0 + 5 Combine like terms: 0 + 5 = 5 40X + X2 = 5 The X term is 40X. Take half its coefficient (20). Square it (400) and add it to both sides. Add '400' to each side of the equation. 40X + 400 + X2 = 5 + 400 Reorder the terms: 400 + 40X + X2 = 5 + 400 Combine like terms: 5 + 400 = 405 400 + 40X + X2 = 405 Factor a perfect square on the left side: (X + 20)(X + 20) = 405 Calculate the square root of the right side: 20.124611797 Break this problem into two subproblems by setting (X + 20) equal to 20.124611797 and -20.124611797.Subproblem 1
X + 20 = 20.124611797 Simplifying X + 20 = 20.124611797 Reorder the terms: 20 + X = 20.124611797 Solving 20 + X = 20.124611797 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + X = 20.124611797 + -20 Combine like terms: 20 + -20 = 0 0 + X = 20.124611797 + -20 X = 20.124611797 + -20 Combine like terms: 20.124611797 + -20 = 0.124611797 X = 0.124611797 Simplifying X = 0.124611797Subproblem 2
X + 20 = -20.124611797 Simplifying X + 20 = -20.124611797 Reorder the terms: 20 + X = -20.124611797 Solving 20 + X = -20.124611797 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-20' to each side of the equation. 20 + -20 + X = -20.124611797 + -20 Combine like terms: 20 + -20 = 0 0 + X = -20.124611797 + -20 X = -20.124611797 + -20 Combine like terms: -20.124611797 + -20 = -40.124611797 X = -40.124611797 Simplifying X = -40.124611797Solution
The solution to the problem is based on the solutions from the subproblems. X = {0.124611797, -40.124611797}
