Given:
Remove the parenthesis, we get;
Like terms are the those terms with same variable and powers.
Combine like terms;
To write this polynomial in standard form, you write starting with the term with the highest degree, or exponent(i.e ), and then in decreasing order .
Standard form:
To, classify a polynomial by degree, you just look at the highest exponent, or degree.
Since, 3 is the highest degree (), it is a cubic.
Now, classify a polynomial by the number of terms, count how many terms are in the polynomial( )
Number of terms: 4 (so this is polynomial)

Similarly,
for
Remove the parenthesis, we get;
Combine like terms; we have
Standard form:
Degree of the polynomial is, 2
Number of terms: 3 ( so, this is trinomial)
