Answer
The answer is below.
Work Step by Step
In order to solve each of the equations, we first factor the equation. Then, we set each factor equal to zero in order to solve:
a) $(n+12)(n+18) \\ n =-12, -18 $
b) $(n+21)(n+14) \\ n =-21, -14 $
c) $(n-16)(n-24) \\ n =16, 24 $
d) $(n-15)(n-25) \\ n =15, 25 $
e) $(n-18)(n+24) \\ n =18, -24 $
f) $(n+16)(n-32) \\ n =-16,32 $
