Simplifying x2 + 11x + 5 = 0 Reorder the terms: 5 + 11x + x2 = 0 Solving 5 + 11x + 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 + 11x + -5 + x2 = 0 + -5 Reorder the terms: 5 + -5 + 11x + x2 = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 11x + x2 = 0 + -5 11x + x2 = 0 + -5 Combine like terms: 0 + -5 = -5 11x + x2 = -5 The x term is 11x. Take half its coefficient (5.5). Square it (30.25) and add it to both sides. Add '30.25' to each side of the equation. 11x + 30.25 + x2 = -5 + 30.25 Reorder the terms: 30.25 + 11x + x2 = -5 + 30.25 Combine like terms: -5 + 30.25 = 25.25 30.25 + 11x + x2 = 25.25 Factor a perfect square on the left side: (x + 5.5)(x + 5.5) = 25.25 Calculate the square root of the right side: 5.024937811 Break this problem into two subproblems by setting (x + 5.5) equal to 5.024937811 and -5.024937811.Subproblem 1
