@Apu
In the question it's given let p,q be two postive numbers that's why.
omg i dint even see it
still my points stands
they are +ve
so there shouldnt be any solution at all
The roots are complex so square can be negative
what
it is stated that p and q are +ve number and +ve numbers cant be complex
yeah
There shouldn't be solution
and sum of square of +ve numbers is always +ve
