Question

1. write the expanded form of. x+y²?​

Answer 1

Answer: Correct option is

C

trinomial

Monomial can be defined as algrebraic expression consisting one term.

Binomial can be defined as algrebraic expression consisting two terms.

Trinomial can be defined as algrebraic expression consisting three terms.

⇒ (x+y)  

2

can be written as (x+y)(x+y)

= x(x+y)+y(x+y)

= x  

2

 + xy + xy +y  

2

 

Add like terms and we get:

= x  

2

 + 2xy + y  

2

 

Rearrange the terms and we get:

= x  

2

 + y  

2

+ 2xy

Hence, in this way we obtain the identity as trinomial i.e 3 terms x  

2

,y  

2

 and 2xy
