Question

Prove that (a-b)^2 = a^2 -2ab+b^2...

Answer 1

Heya !!

$(a-b)^2 = (a-b)(a-b)\\\\= a^2 - ab - ba + b^2\\\\= a^2 -ab - ab + b^2 \\\\= a^2 - 2ab + b^2\\\\\text{Hence Proved !!}$

Hope it helps !!

Answer 2

To Prove = a² - 2 ab + b²

( a - b )² = a² - 2 ab + b²

a² - ab - ba + b²

a² - ab - ab + b²

a² - 2 ab + b²


Hence ,

PROVED
