What is a quartic function with only the two real zeros given? x=-4 and x=-1

The quartic function is:

Quartic function--

A quartic function is a polynomial function with degree 4.

Now we know that for any quartic funtcion with just two roots "a" and "b" the equation of the function is calculated as:

Here let a= -4 and b= -1

Hence, the equation of  a quartic function is calculated as follows:

Now as we know that:

Hence,

and

Hence,

on combining like terms we have:
