If p(x)=x^2-3x+2x^3+5 and q(x)=x^2+2x+4,...

If p(x)=x^2-3x+2x^3+5 and q(x)=x^2+2x+4, the find p(x)+q(x).

Text Solution

Verified by Experts

The correct Answer is:
A, D
Since, `(2x-1)/(2x^(3)+3x^(2)+x)gt0`
`rArr ((2x-1))/(x(2x^(2)+3x+1)) gt0`
`rArr((2x-1))/(x(2x+1)(x+1)) gt 0`

Hence, the solution set is,
` x in (-oo,-1) cup (-1//2,0) cup (1//2,oo)`
Hence, (a) and (d) are the correct options.
