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

1.	How much does 93p2 -55p+4 exceed 13p3 -5p2 + 17p-90?
Answer» 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.

Answer»

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.
