Question

How much does 93p² – 55p + 4 exceed 13p³ – 5p² + 17p – 90?

Answer 1

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.
