Two zeros are alfa & bita,Alfa/bita =2/3,alfa =2k & bita = 3k,alfa+bita = -b/a so, p = 5k & alfa.bita = c/a so, q = 6k^2,Hence, 6*5*5*k^2 = 25*6*k^2,So LHS = RHS

Hello mate,
Here is your answer,
Let the zeroes be 2a and 3a.
Sum of 0's
p = 5a
a = p/5
Product of 0's
q = 6a2
q = 6(p/5)2
q = 6p2/25
6p2=25q
