Simplifying x2 + 40x + 17 = 0 Reorder the terms: 17 + 40x + x2 = 0 Solving 17 + 40x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-17' to each side of the equation. 17 + 40x + -17 + x2 = 0 + -17 Reorder the terms: 17 + -17 + 40x + x2 = 0 + -17 Combine like terms: 17 + -17 = 0 0 + 40x + x2 = 0 + -17 40x + x2 = 0 + -17 Combine like terms: 0 + -17 = -17 40x + x2 = -17 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 = -17 + 400 Reorder the terms: 400 + 40x + x2 = -17 + 400 Combine like terms: -17 + 400 = 383 400 + 40x + x2 = 383 Factor a perfect square on the left side: (x + 20)(x + 20) = 383 Calculate the square root of the right side: 19.570385791 Break this problem into two subproblems by setting (x + 20) equal to 19.570385791 and -19.570385791.Subproblem 1
x + 20 = 19.570385791 Simplifying x + 20 = 19.570385791 Reorder the terms: 20 + x = 19.570385791 Solving 20 + x = 19.570385791 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 = 19.570385791 + -20 Combine like terms: 20 + -20 = 0 0 + x = 19.570385791 + -20 x = 19.570385791 + -20 Combine like terms: 19.570385791 + -20 = -0.429614209 x = -0.429614209 Simplifying x = -0.429614209Subproblem 2
x + 20 = -19.570385791 Simplifying x + 20 = -19.570385791 Reorder the terms: 20 + x = -19.570385791 Solving 20 + x = -19.570385791 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 = -19.570385791 + -20 Combine like terms: 20 + -20 = 0 0 + x = -19.570385791 + -20 x = -19.570385791 + -20 Combine like terms: -19.570385791 + -20 = -39.570385791 x = -39.570385791 Simplifying x = -39.570385791Solution
