Question

plz solve this problem ​

Answer 1

Answer:

Step-by-step explanation:

Theory of equations:-

Given a quadratic equation with roots exceeding a particular value.

First,we apply the condition discriminant is greater than 0.

We get a range of a.

Then roots of the equation are greater than a.For this,we need to apply f(a)>0,where a is the specified number and f(x)=0 is the quadratic equation.We get another range of a.

Finding the intersection of two ranges,we get a<-2.

Hence,D option is correct.
