Answer :

In the given term


Dividend = (4l5 – 6l4 + 8l3)


Take out the common part in binomial term


= (2 × 2 × l × l × l × l × l– 3 × 2 × l × l × l × l + 2 × 2 × 2 × l × l × l )


= (2l2 – 3l + 4)2l3


Divisor = 2l2


=


= (2l2 – 3l + 4)l


= (2l3 –2l2 + 4l)


Hence dividing 4(l5 – 6l4 + 8l3) by 2l2 gives out (2l3 –2l2 + 4l)
