Answer 1

Answer:

It's given correct.

Step-by-step explanation:

For suppose, take any example of a polynomial in variable x that means , the polynomial should contain only the variable 'x'. For example => x²+5x-3 (given in the photo) or you can take any other example. So,when we denote that polynomial while solving it , we need not write the whole polynomial everytime. We can represent it as P(x) that means

Here, P refers to polynomial and x in the brackets refers to the variable that is there in the polynomial. For the polynomial we may use any other alphabet such as Q . So, it may also be represented as Q(x)
