I want full explanation




and also the 8th one

guys please answer me​

Answer 1

Answer:

Step-by-step explanation:

product of roots  = c / a =[2-i ] /i = [ 2-i ] [ 1/i ]

given one root   2-i    then other root = 1/i = - i

Answer 2

Answer:

8)p=1 , q= 0

Step-by-step explanation:

Sum of roots = p+q =p

=> q=p-p

=> q=0

Product of roots = pq = q

=>p= q/q

=>p= 1

•

• • p=1 , q= 0
