I'd like to see some of your own efforts here. This is the third time you've posted two "factor completelyl" problems, without sharing what you've already done.
<span>3v^2 - 8v - 16 cannot be reduced. Thus, your best choice to find roots is to apply the quadratic formula:
8 plus or minus sqrt( 64-4(3)(-16) )
v = ---------------------------------------------------
2(3)
8 plus or minus sqrt( 64 + 192 )
= ---------------------------------------------
6
8 plus or minus sqrt(256)
= -------------------------------------
6
= 8 + 16, all divided by 6, or 8 - 16, all divided by 6
= 4 or -8/6, or 4 or -4/3.
The factors are (v-4) and (v + 4/3).</span>

Step-by-step explanation:
Given
There are total 40 students in a class
No of students with Pierced Nose n(N)=7
No of students with Pierced ear n(E)=36
and we know using sets
where 
Students either nose or ear Pierced
no of students having both nose and ear pierced
