Question

if p and q are the roots of the equation x square- px +q =0 then p and q
p= 1 , q= 2
p=-2, q=0
p=0 ,q=1
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.
