QTY A::

\((x^2+1)\)\((x+1)\)

QTY B::

\((x+1)^2(x-1)\) = \((x+1)(x+1)(x-1)\)

REMOVING x+1 from both quantities

QTY A : \((x^2+1)\)

QTY B : \((x+1)(x-1)\) = \((x^2-1) \)

Therefore QTY A > QTY B

Sir,

How to divide \((x^2+1)(x+1)\) by \(x-1\) ?

(x^2+1) follows A^2+B^2=(A-B)(A+B)
(x^2+1^2)=(x-1)(x+1)
