I didnt quite follow your solution. can u elaborate?

If d is a perfect square, then it is not necessary that the roots themselves will be integral. It cud even end up as a fraction, don't you think?
for example, if d is a perfect square, like 25, then its sqrt will be 5. But then it is not necessary that -b +/- sqrt d / (2a) needs to be integral...

for question one, I got the value of a = -2.
Roots are 3, 0.
Discriminant of the equation = a^2 + 2a + 9.
roots will be -b +/- sqrt (d) / 2a.
I know my solution looks ugly, but first tell me if my answer is right.

This thing does not give you a clear picture. Wait for the real counselling to start.

I hope you know that 5^2n divided by 13 gives remainder 12.
here, 23^15 = 5^30 = 5^2x15 = 5^2n.
Thus the remainder in this case will be 12.

See... It depends on what you want to do. If you have more interest in ece, which i think is a more popular branch, then you should go for ece, and amritha is a pretty good institute. However, if you like stuff about buildings and construction, then you should opt for nit. It depends on your liking.

Nice article dude

For all such sums, the answer is 2^n. As the expert said above, you have to put a =b=1.

we are given the two roots. Since they are the roots of the equation, each of them must satisfy the equation.
Therefore, putting 2 in place of x, we get :
8 + 4q + 22 - p = 0 => 4q-p = -30
Also,
27 + 9q + 33 - p = 0 => 9q-p = -60
solving the two equations in p and q, we get :
q = -6, p = 10.
