Simplifying n2 + 4n + -69 = 0 Reorder the terms: -69 + 4n + n2 = 0 Solving -69 + 4n + n2 = 0 Solving for variable 'n'. Begin completing the square. Move the constant term to the right: Add '69' to each side of the equation. -69 + 4n + 69 + n2 = 0 + 69 Reorder the terms: -69 + 69 + 4n + n2 = 0 + 69 Combine like terms: -69 + 69 = 0 0 + 4n + n2 = 0 + 69 4n + n2 = 0 + 69 Combine like terms: 0 + 69 = 69 4n + n2 = 69 The n term is 4n. Take half its coefficient (2). Square it (4) and add it to both sides. Add '4' to each side of the equation. 4n + 4 + n2 = 69 + 4 Reorder the terms: 4 + 4n + n2 = 69 + 4 Combine like terms: 69 + 4 = 73 4 + 4n + n2 = 73 Factor a perfect square on the left side: (n + 2)(n + 2) = 73 Calculate the square root of the right side: 8.544003745 Break this problem into two subproblems by setting (n + 2) equal to 8.544003745 and -8.544003745.Subproblem 1
n + 2 = 8.544003745 Simplifying n + 2 = 8.544003745 Reorder the terms: 2 + n = 8.544003745 Solving 2 + n = 8.544003745 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + n = 8.544003745 + -2 Combine like terms: 2 + -2 = 0 0 + n = 8.544003745 + -2 n = 8.544003745 + -2 Combine like terms: 8.544003745 + -2 = 6.544003745 n = 6.544003745 Simplifying n = 6.544003745Subproblem 2
n + 2 = -8.544003745 Simplifying n + 2 = -8.544003745 Reorder the terms: 2 + n = -8.544003745 Solving 2 + n = -8.544003745 Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + n = -8.544003745 + -2 Combine like terms: 2 + -2 = 0 0 + n = -8.544003745 + -2 n = -8.544003745 + -2 Combine like terms: -8.544003745 + -2 = -10.544003745 n = -10.544003745 Simplifying n = -10.544003745Solution
