Q. 17

Mark the Correct alternative in the following:

The value of p and q for which p, q are the roots of the equation are

A. p = 1, q = 2

B. p = 1, q = 2

C. p = 1, q = 2

D. p = 1, q = 2

Answer :

Sum of the roots = = -p

p + q = -p …(1)


Product of the roots = = q


pq = q


p = 1


Put value of p in eq.(1)


1 + q = -1


q = -2
