Remainder Theorem: when a polynomial <em>P(x) </em>is divided <em>by (x - a), </em>the remainder is <em>P(a).</em>
<em />
Given expression:

In this case:


To know the reminder, we have to plug in the value of <em>z </em>in the polynomial:

Simplifying:



Answer: The remainder is 15.
1 is B
2 is A.fes.fdsf.ef.sf.esf.esfs.ef
I think it’s 1. If wrong sorry
