Question

If p and q are the roots of the equation x2-px+q=0, then

a) p=1, q=-2 b) p=0, q=1 c) p=-2, q=0 d) p=-2, q=1​

Answer 1

Answer:

Given equation

x

2

+px+q

Also, given p,q are the roots of the equation.

p+q=−p

2p=−q .....(1)

And pq=q

q(p−1)=0

⇒q=0 or p=1

So, by (1), q=0⇒p=0

Hence, the values of p are 0,1.
