Mark the Correct alternative in the following:
If α, β are the roots of the equation 
, then 
are the roots of the equation
A. 
B. 
C. 
D. 
Answer :
from the given equation sum of the roots α + β = - p
Product of roots αβ = q
Formula to form a quadratic equation is x2- (α + β) x+ αβ = 0
Where α, β are roots of equation.
Given 
are roots, then required quadratic equation is
qx2 – px + 1 = 0.
