Simplifying (5 + n)(3 + n) = 48 Multiply (5 + n) * (3 + n) (5(3 + n) + n(3 + n)) = 48 ((3 * 5 + n * 5) + n(3 + n)) = 48 ((15 + 5n) + n(3 + n)) = 48 (15 + 5n + (3 * n + n * n)) = 48 (15 + 5n + (3n + n2)) = 48 Combine like terms: 5n + 3n = 8n (15 + 8n + n2) = 48 Solving 15 + 8n + n2 = 48 Solving for variable 'n'. Reorder the terms: 15 + -48 + 8n + n2 = 48 + -48 Combine like terms: 15 + -48 = -33 -33 + 8n + n2 = 48 + -48 Combine like terms: 48 + -48 = 0 -33 + 8n + n2 = 0 Factor a trinomial. (-11 + -1n)(3 + -1n) = 0Subproblem 1
Set the factor '(-11 + -1n)' equal to zero and attempt to solve: Simplifying -11 + -1n = 0 Solving -11 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + -1n = 0 + 11 Combine like terms: -11 + 11 = 0 0 + -1n = 0 + 11 -1n = 0 + 11 Combine like terms: 0 + 11 = 11 -1n = 11 Divide each side by '-1'. n = -11 Simplifying n = -11Subproblem 2
Set the factor '(3 + -1n)' equal to zero and attempt to solve: Simplifying 3 + -1n = 0 Solving 3 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -1n = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1n = 0 + -3 -1n = 0 + -3 Combine like terms: 0 + -3 = -3 -1n = -3 Divide each side by '-1'. n = 3 Simplifying n = 3Solution
n = {-11, 3}
