Answer:

Step-by-step explanation:
We have been given a polynomial
and we are supposed to simplify our polynomial.
We will use factoring to simplify our polynomial. Let us factor out the greatest common factor of all the terms.
We can see that 16, 6 and 4 has 2 as their greatest common factor.
The greatest common factor of
is r.
The greatest common factor of
is t.
So the greatest common factor of the terms of our expression will be
.
Let us factor out
from our given polynomial.

As we can not factor our expression more, therefore, we will get
after simplifying our polynomial.
