Question

pls answer this step by step ​

Answer 1

Answer:

Given that p and q are the roots of x

2

+px+q=0

step by step

Then, using sum and product of roots, we have

p+q=−p

2p=−q ....(i)

pq=q ....(ii)

Putting the value of q in equation (ii), we get

p(−2p)=−2p

⇒2p

2

=2p

⇒p=1

Substituting this value in equation (i), we get

2(1)=−q

⇒q=−2

Thus p=1 and q=−2.
