A) \[(p-3pq)\]
B) \[{{p}^{3}}+3pq\]
C) \[{{p}^{3}}-3qp\]
D) \[3p-{{q}^{3}}\]
Correct Answer: C
Solution :
We have \[\alpha +\beta =p\]and \[\alpha \beta =q\] \[({{\alpha }^{3}}+{{\beta }^{3}})=(\alpha +{{\beta }^{3}})-3\alpha \beta \,\,(\alpha +\beta )=({{p}^{3}}-3qp)\]You need to login to perform this action.
