Simplifying n2 + 6n + -75 = -5 Reorder the terms: -75 + 6n + n2 = -5 Solving -75 + 6n + n2 = -5 Solving for variable 'n'. Reorder the terms: -75 + 5 + 6n + n2 = -5 + 5 Combine like terms: -75 + 5 = -70 -70 + 6n + n2 = -5 + 5 Combine like terms: -5 + 5 = 0 -70 + 6n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '70' to each side of the equation. -70 + 6n + 70 + n2 = 0 + 70 Reorder the terms: -70 + 70 + 6n + n2 = 0 + 70 Combine like terms: -70 + 70 = 0 0 + 6n + n2 = 0 + 70 6n + n2 = 0 + 70 Combine like terms: 0 + 70 = 70 6n + n2 = 70 The n term is 6n. Take half its coefficient (3). Square it (9) and add it to both sides. Add '9' to each side of the equation. 6n + 9 + n2 = 70 + 9 Reorder the terms: 9 + 6n + n2 = 70 + 9 Combine like terms: 70 + 9 = 79 9 + 6n + n2 = 79 Factor a perfect square on the left side: (n + 3)(n + 3) = 79 Calculate the square root of the right side: 8.888194417 Break this problem into two subproblems by setting (n + 3) equal to 8.888194417 and -8.888194417.Subproblem 1
n + 3 = 8.888194417 Simplifying n + 3 = 8.888194417 Reorder the terms: 3 + n = 8.888194417 Solving 3 + n = 8.888194417 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + n = 8.888194417 + -3 Combine like terms: 3 + -3 = 0 0 + n = 8.888194417 + -3 n = 8.888194417 + -3 Combine like terms: 8.888194417 + -3 = 5.888194417 n = 5.888194417 Simplifying n = 5.888194417Subproblem 2
n + 3 = -8.888194417 Simplifying n + 3 = -8.888194417 Reorder the terms: 3 + n = -8.888194417 Solving 3 + n = -8.888194417 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + n = -8.888194417 + -3 Combine like terms: 3 + -3 = 0 0 + n = -8.888194417 + -3 n = -8.888194417 + -3 Combine like terms: -8.888194417 + -3 = -11.888194417 n = -11.888194417 Simplifying n = -11.888194417Solution
