n%2F%28n-4%29%2Bn=12-4n%2F%28n-4%29………multiply both sides by n-4
%28n%28n-4%29%2F%28n-4%29%29+%2Bn+%28n-4%29+=12%28n-4%29+-+4n%28n-4%29%2F%28n-4%29………simplify, and multiply
………

n%2Bn%5E2-4n+=+12n-48-4n………

n%5E2-11n%2B48=+0………



the roots are:

n%5B1%2C2%5D=%28-b+%2B-+sqrt+%28b%5E2+-4%2Aa%2Ac+%29%29+%2F+%282%2Aa%29

n%5B1%2C2%5D=%28-%28-11%29+%2B-+sqrt+%28%28-11%29%5E2+-4%2A1%2A48+%29%29+%2F+%282%2A1%29
n%5B1%2C2%5D=%2811+%2B-+sqrt+%28121+-+192+%29%29+%2F+2
n%5B1%2C2%5D=%2811+%2B-+sqrt+%28-71+%29%29+%2F+2
n%5B1%2C2%5D=%2811+%2B-+sqrt+%2871%28-1%29+%29%29+%2F+2
n%5B1%2C2%5D=%2811+%2B-+8.4i+%29+%2F+2


n%5B1%5D=%2811+%2B+8.4i+%29+%2F+2
n%5B1%5D=+5.5+%2B+4.2i

n%5B2%5D=%2811+-+8.4i+%29+%2F+2
n%5B2%5D=+5.5+-+4.2i
