Question

Verify the all algebraic identity (a+b)^2 = a^2 + 2ab + b^2 by an activity method.​

Answer 1

Step-by-step explanation:

See How to solve:

Basically we take an example

(x+y)^2

So,

We will take first x and we will write (x)^2.

Then we will take y and we will write (y)^2.

Now see,

Two terms are there (x)^2 and (y)^2

Then we have to write (x)^2+ 2 (x)×(y)+ (y)^2

So now we have to solve so what will come:

x^2+2xy+y^2

This way we solve.

I hope this explanation help you.
