Simplifying x2 + -40x + 11 = 0 Reorder the terms: 11 + -40x + x2 = 0 Solving 11 + -40x + x2 = 0 Solving for variable 'x'. Begin completing the square. Move the constant term to the right: Add '-11' to each side of the equation. 11 + -40x + -11 + x2 = 0 + -11 Reorder the terms: 11 + -11 + -40x + x2 = 0 + -11 Combine like terms: 11 + -11 = 0 0 + -40x + x2 = 0 + -11 -40x + x2 = 0 + -11 Combine like terms: 0 + -11 = -11 -40x + x2 = -11 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 = -11 + 400 Reorder the terms: 400 + -40x + x2 = -11 + 400 Combine like terms: -11 + 400 = 389 400 + -40x + x2 = 389 Factor a perfect square on the left side: (x + -20)(x + -20) = 389 Calculate the square root of the right side: 19.723082923 Break this problem into two subproblems by setting (x + -20) equal to 19.723082923 and -19.723082923.Subproblem 1
x + -20 = 19.723082923 Simplifying x + -20 = 19.723082923 Reorder the terms: -20 + x = 19.723082923 Solving -20 + x = 19.723082923 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 = 19.723082923 + 20 Combine like terms: -20 + 20 = 0 0 + x = 19.723082923 + 20 x = 19.723082923 + 20 Combine like terms: 19.723082923 + 20 = 39.723082923 x = 39.723082923 Simplifying x = 39.723082923Subproblem 2
x + -20 = -19.723082923 Simplifying x + -20 = -19.723082923 Reorder the terms: -20 + x = -19.723082923 Solving -20 + x = -19.723082923 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 = -19.723082923 + 20 Combine like terms: -20 + 20 = 0 0 + x = -19.723082923 + 20 x = -19.723082923 + 20 Combine like terms: -19.723082923 + 20 = 0.276917077 x = 0.276917077 Simplifying x = 0.276917077Solution
