Degree of a polynomial is the highest power of the variable in the polynomial.
Binomial has two terms in it.
Therefore, binomial of degree 35 can be written as x35 + x34. Monomial has only one term in it.
Therefore, monomial of degree 100 can be written as x 100 .
Write the coefficients of x 2 in each of the following:
(i) 2 + x 2 + x
(ii) 2 – x 2 + x 3
(iii) \(\frac{π }{ 2}\) x2 + x
(iv) √2 x -1

(iv) y +\(\frac{ 2 }{ y} \)
(v) x 10 + y 3 + t 50
