Simplifying (n + 5)(n + -7) = 28 Reorder the terms: (5 + n)(n + -7) = 28 Reorder the terms: (5 + n)(-7 + n) = 28 Multiply (5 + n) * (-7 + n) (5(-7 + n) + n(-7 + n)) = 28 ((-7 * 5 + n * 5) + n(-7 + n)) = 28 ((-35 + 5n) + n(-7 + n)) = 28 (-35 + 5n + (-7 * n + n * n)) = 28 (-35 + 5n + (-7n + n2)) = 28 Combine like terms: 5n + -7n = -2n (-35 + -2n + n2) = 28 Solving -35 + -2n + n2 = 28 Solving for variable 'n'. Reorder the terms: -35 + -28 + -2n + n2 = 28 + -28 Combine like terms: -35 + -28 = -63 -63 + -2n + n2 = 28 + -28 Combine like terms: 28 + -28 = 0 -63 + -2n + n2 = 0 Factor a trinomial. (-7 + -1n)(9 + -1n) = 0Subproblem 1
Set the factor '(-7 + -1n)' equal to zero and attempt to solve: Simplifying -7 + -1n = 0 Solving -7 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '7' to each side of the equation. -7 + 7 + -1n = 0 + 7 Combine like terms: -7 + 7 = 0 0 + -1n = 0 + 7 -1n = 0 + 7 Combine like terms: 0 + 7 = 7 -1n = 7 Divide each side by '-1'. n = -7 Simplifying n = -7Subproblem 2
Set the factor '(9 + -1n)' equal to zero and attempt to solve: Simplifying 9 + -1n = 0 Solving 9 + -1n = 0 Move all terms containing n to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -1n = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -1n = 0 + -9 -1n = 0 + -9 Combine like terms: 0 + -9 = -9 -1n = -9 Divide each side by '-1'. n = 9 Simplifying n = 9Solution
n = {-7, 9}
