Answer:

The solutions are:

#color(blue)( n =0#

# color(blue)(n =13#

Explanation:

#13n - n^2 =0#

Multiplying the entire equation by #-1#:

# n^2 - 13n =0#

#n# is common to both terms of the L.H.S :

# n ( n - 13 ) =0#

Equating each of the factors to zero, we obtain the solutions:

#color(blue)( n =0#

# n - 13 =0, color(blue)(n =13#

Answer:

#n=0 or n=13#

Explanation:

Start by factorizing to get

#n(13-n)=0#

#therefore n=0 or n=13#
