Simplifying n2 + 4n = 40 Reorder the terms: 4n + n2 = 40 Solving 4n + n2 = 40 Solving for variable 'n'. Reorder the terms: -40 + 4n + n2 = 40 + -40 Combine like terms: 40 + -40 = 0 -40 + 4n + n2 = 0 Begin completing the square. Move the constant term to the right: Add '40' to each side of the equation. -40 + 4n + 40 + n2 = 0 + 40 Reorder the terms: -40 + 40 + 4n + n2 = 0 + 40 Combine like terms: -40 + 40 = 0 0 + 4n + n2 = 0 + 40 4n + n2 = 0 + 40 Combine like terms: 0 + 40 = 40 4n + n2 = 40 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 = 40 + 4 Reorder the terms: 4 + 4n + n2 = 40 + 4 Combine like terms: 40 + 4 = 44 4 + 4n + n2 = 44 Factor a perfect square on the left side: (n + 2)(n + 2) = 44 Calculate the square root of the right side: 6.633249581 Break this problem into two subproblems by setting (n + 2) equal to 6.633249581 and -6.633249581.Subproblem 1
n + 2 = 6.633249581 Simplifying n + 2 = 6.633249581 Reorder the terms: 2 + n = 6.633249581 Solving 2 + n = 6.633249581 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 = 6.633249581 + -2 Combine like terms: 2 + -2 = 0 0 + n = 6.633249581 + -2 n = 6.633249581 + -2 Combine like terms: 6.633249581 + -2 = 4.633249581 n = 4.633249581 Simplifying n = 4.633249581Subproblem 2
n + 2 = -6.633249581 Simplifying n + 2 = -6.633249581 Reorder the terms: 2 + n = -6.633249581 Solving 2 + n = -6.633249581 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 = -6.633249581 + -2 Combine like terms: 2 + -2 = 0 0 + n = -6.633249581 + -2 n = -6.633249581 + -2 Combine like terms: -6.633249581 + -2 = -8.633249581 n = -8.633249581 Simplifying n = -8.633249581Solution
