Answer:
(n + 7)(n + 2) = 0
Step-by-step explanation:
Set the equation equal to 0. Add 14 to both sides:
n² + 9n = -14
n² + 9n (+14) = -14 (+14)
n² + 9n + 14 = 0
Find factors of 14 & n, that, when combined, will equal 9n.
n² + 9n + 14 = 0
n 7
n 2
(n + 7)(n + 2) = 0
(n + 7)(n + 2) = 0 is your answer.
