Here in the correct answer, option D says we can get Q (minimum point) by using P & R (roots).

When we take equation

y = x^2 - 5x + 6 minimum point is (2.5, -0.25)

y = 2x^2 - 10x + 12 minimum point is (2.5, -0.5)

Both have same P & R i.e. (3, 0), (2, 0)

For same P & R, we get different Q.

Can you please help regarding this?
