Simplifying -1x2 + 11x + -16 = 0 Reorder the terms: -16 + 11x + -1x2 = 0 Solving -16 + 11x + -1x2 = 0 Solving for variable 'x'. Begin completing the square. Divide all terms by -1 the coefficient of the squared term: Divide each side by '-1'. 16 + -11x + x2 = 0 Move the constant term to the right: Add '-16' to each side of the equation. 16 + -11x + -16 + x2 = 0 + -16 Reorder the terms: 16 + -16 + -11x + x2 = 0 + -16 Combine like terms: 16 + -16 = 0 0 + -11x + x2 = 0 + -16 -11x + x2 = 0 + -16 Combine like terms: 0 + -16 = -16 -11x + x2 = -16 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 = -16 + 30.25 Reorder the terms: 30.25 + -11x + x2 = -16 + 30.25 Combine like terms: -16 + 30.25 = 14.25 30.25 + -11x + x2 = 14.25 Factor a perfect square on the left side: (x + -5.5)(x + -5.5) = 14.25 Calculate the square root of the right side: 3.774917218 Break this problem into two subproblems by setting (x + -5.5) equal to 3.774917218 and -3.774917218.Subproblem 1
x + -5.5 = 3.774917218 Simplifying x + -5.5 = 3.774917218 Reorder the terms: -5.5 + x = 3.774917218 Solving -5.5 + x = 3.774917218 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
