In dashcat 17, Q47 which is as follows: Minimum difference b/w 2 integers p & q (p>q) , equation ((q^2)+12p-3)>0 is positive? Why, in the video solution Discriminant (D) is taken as <0 (less than 0). Can you please explain??

Question

Answer 1

When any quadratic equation is greater than zero, its discriminant have to be less than zero and if any quadratic equation is less than zero,its discriminant is greater than zero. Just remember this. Apply everywhere if need.

Answer 2

When any quadratic equation is greater than zero, its discriminant have to be less than zero and if any quadratic equation is less than zero,its discriminant is greater than zero. Just remember this. Apply everywhere if need.

Answer 3
