Question

pls tell me thee answer​

Answer 1

Answer:

I. If you want to factorise:-

y² + y²

(Given as per the question)

= (y)(y+y)

(Taken y as common)

= (2y)(y)

(Answer)

II. If you want to evaluate:-

Given in the algebraic expressions, there are two like terms that is (y²). We can add them.

y² + y²

(Algebraic expression per the question)

= 2y²

(Evaluated)

_________________...

Doubts:-

(Will help in case of Case II)

If any such problems arise, you've to add a coefficient. See the example below:-

4² + 4² + 4²

[Consider an expression (4² + 4² + 4²)]

= 3(4²)

(We can also compress it)

Similar thing happens while evaluation of the like terms.
