Answer:

We know the Formulae:

a² + b² = (a+b)² - 2ab

It's derived from the main formulae

(a+b)² = a² + 2ab + b²

Now, let's put the (+ 2ab) on the left side:

(a+b)² - 2ab = a² + b²

                        -------That's the ANS

If you find anything Wrong, Please pardon me and let me know about it.

And, if it proved helpful to you, Please give it a BRAINLIEST.

Thank you EVERYONE, for EVERYTHING!!
