उत्तर
Required expression is
93p2 – 55p + 4 – (13p3 – 5p2 + 17p – 90)
= 93p2 – 55p + 4 – 13p3 + 5p2 – 17p + 90
On combining the like terms,
= 93p2 + 5p2 – 55p – 17p + 4 + 90 – 13p3
= 98p2 – 72p + 94 – 13p3
= –13p3 + 98p2 – 72p + 94
So, 93p2 – 55p + 4 is –13p3 + 9p2 – 72p + 94 exceed from 13p3 – 5p2 + 17p – 90.
