P(s) =
3 {s}^{2}  +  {s}^{2}  - 20s + 12
we have to check whether p(s) is multiple of
g(s)=
3s - 2
If p(s) is a multiple of g(s) then upon dividing P(s) by g(s) the remainder would be zero.

Applying Remainder theorem

3s - 2 = 0
S = 2/3

then P(2/3) =
3 \times  \ \frac{ {2}^{2} }{ {3}^{2} }   +  \frac{ {2}^{2} }{ {3}^{2} }  - 20 \times  \frac{2}{3}  + 12
=
 \frac{4}{9}

So , Remainder is
 \frac{4}{9}
Not 0 so , p(s) is not multiple of g(s).
