A) \[{{p}^{2}}=4q\]
B) \[{{p}^{2}}=4q+1\]
C) \[{{p}^{2}}=4q-1\]
D) None of these
Correct Answer: B
Solution :
Let the roots of the equation be\[\alpha ,\beta \] Given \[\alpha -\beta =1\] \ \[{{(\alpha -\beta )}^{2}}={{(\alpha +\beta )}^{2}}-4\alpha \beta \] Þ \[{{(1)}^{2}}={{(-p)}^{2}}-4q\] \ \[{{p}^{2}}=4q+1\].You need to login to perform this action.
