`(p^(2)-p)/(2p^(3)+p^(2))+(p^(2)-1)/(p^(2)-3p)+(p^(2))/(p+1)` का साधारणीकृत मान क्‍या है?

Options

A. `2p^(2)`
B. `1/(2p^(2))`
C. `p+3`
D. `1/(p+3`

Answer

B

Explanation

`(p^(2)-p)/(2p^(3)+p^(2))+(p^(2)-1)/(p^(2)+3p)+(p^(2))/(p+1)`
In such type of question assume values of `p`
`:.` Let `p=1`
`:. (1-1)/(2+1)+(1-1)/(1+3)+1/(1+1)`
`=0+0+1/2=1/2`
Now check options b
`1/(2p^(2))=1/2`
Hence option b is answer:
