Answer:
Standard form
Name the polynomial based on its degree is cubic polynomial
Name the polynomial based on number of terms is trinomial.
Step-by-step explanation:
Consider the given polynomial
We have to write the polynomial in standard form and Then name the polynomial based on its degree and number of terms.
Consider the given polynomial
We first simplify the given polynomial by adding like terms,
LIKE TERMS are term having same variable with same power.
Here, are like terms,
Thus adding both we get,
Thus, polynomial becomes,
In standard form, terms are arranged in decreasing order of power of variables.
can be written as
Thus, the given polynomial has highest power of 3 so its a cubic polynomial on the basis of degree.
and Since, it consist of three terms so it is a trinomial on the basis of number of terms.
