Explanation:

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
