Now, we are going to derive the equation.

One of the elementary formula in high school mathematics, most of us know this formula. But do we actually know why?

(a+b)^{2} = a^{2} + b^{2} + 2ab

First of all we have to draw a random line and put the random point on it.

Markdown the side as a & b

a+b is equal to this line

We need (a+b)^{2}

So make square of this line

Now it is a (a+b)^{2}

Marking all the points on the place

Now find out area of this square

(a+b)

^{2}= a^{2}+ b^{2}+ 2ab

Done.

Coming out new part of #Mathmagic very soon.
