1. A polynomial containing two non zero terms is called?
2. what degree root 3 have?
3. what is the factor of polynomial 4x^2+y^2+4xy+8x+4y+4?
4. what is a constant polynomial?
5. Number of zeros a cubic polynomial has?

please give the answers

thank you

A polynomial containing two nonzero terms is called a binomial .For example :- (3+6x) , (x-5y)

As root 3 is a constant .Hence it is a polynomial of degree zero.

Factors of polynomial 
$$\begin{gathered} 4x^2+y^2+4xy+8x+4y+4 \\ =(2x{)}^2+(y{)}^2+2\times 2x\times y+8x+4y+4 \\ =(2x+y{)}^2+4(2x+y)+4 \left\{\because (a^2+b^2+2ab =(a+b{)}^2 \right\} \\ =(2x+y{)}^2+2\times (2x+y)\times 2+(2{)}^2 \\ =(2x+y+2{)}^2 \\ Hence factors are (2x+y+2)(2x+y+2) \end{gathered}$$

A polynomial containing one term only ,consisting of a constant is called a constant polynomial .For example:- 3,-8 etc

A cubic polynomial has a maximum of three zeroes according to the fundamental theorem of algebra.
Hence we can say depending upon the cubic polynomial ,it may have 1 zero,2 zeroes and three zeroes but not more than three zeroes.
