Simplifying n2 + -3n + -135 = 0 Reorder the terms: -135 + -3n + n2 = 0 Solving -135 + -3n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '135' to each side of the equation. -135 + -3n + 135 + n2 = 0 + 135 Reorder the terms: -135 + 135 + -3n + n2 = 0 + 135 Combine like terms: -135 + 135 = 0 0 + -3n + n2 = 0 + 135 -3n + n2 = 0 + 135 Combine like terms: 0 + 135 = 135 -3n + n2 = 135 The n term is -3n. Take half its coefficient (-1.5). Square it (2.25) and add it to both sides. Add '2.25' to each side of the equation. -3n + 2.25 + n2 = 135 + 2.25 Reorder the terms: 2.25 + -3n + n2 = 135 + 2.25 Combine like terms: 135 + 2.25 = 137.25 2.25 + -3n + n2 = 137.25 Factor a perfect square on the left side: (n + -1.5)(n + -1.5) = 137.25 Calculate the square root of the right side: 11.715374514 Break this problem into two subproblems by setting (n + -1.5) equal to 11.715374514 and -11.715374514.Subproblem 1
n + -1.5 = 11.715374514 Simplifying n + -1.5 = 11.715374514 Reorder the terms: -1.5 + n = 11.715374514 Solving -1.5 + n = 11.715374514 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = 11.715374514 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = 11.715374514 + 1.5 n = 11.715374514 + 1.5 Combine like terms: 11.715374514 + 1.5 = 13.215374514 n = 13.215374514 Simplifying n = 13.215374514Subproblem 2
n + -1.5 = -11.715374514 Simplifying n + -1.5 = -11.715374514 Reorder the terms: -1.5 + n = -11.715374514 Solving -1.5 + n = -11.715374514 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '1.5' to each side of the equation. -1.5 + 1.5 + n = -11.715374514 + 1.5 Combine like terms: -1.5 + 1.5 = 0.0 0.0 + n = -11.715374514 + 1.5 n = -11.715374514 + 1.5 Combine like terms: -11.715374514 + 1.5 = -10.215374514 n = -10.215374514 Simplifying n = -10.215374514Solution
