The number of quadratic equations ax2+bx+c=0 such that ax2+bx+c+k=0 has two distinct positive roots for each k,where k is real
Dear sudarshan gupta,
Given, ax2+bx+c+k=0, has two distinct positive roots for each k, where k is real
let, p,q be those roots
then p and q are distinct and positive, hence product should be always positive for all real k
but pq=(c+k)/a, which can take both positive and negative values as k changes.
So there will be no quadratic equation ax2+bx+c = 0, such that ax2+bx+c+k=0 has 2 distinct positive roots for each real k.
