1. IF D is negative, THEN the equation has no real roots.

2. IF D is positive, THEN the equation has two real roots.

2. IF D is zero, THEN both the roots of the equation are equal.

Let us discuss a few examples.

Ready?

P.S: What is your feedback about the last line of my signature?

]]>That is not possible. So, neither is it possible to solve for x.

Wait, I'll come back after dinner.

Did you read what NCERT says on Discriminants?

which is

But, again, is it possible to find the square root of a negative number?

I'd like to know what you think

]]>Now, let us examine what are a, b and c.

a is the coefficient of x², b is the coefficent of x and c is the constant term.

In your next reply, I'll be expecting you to tell what are the values of a, b and c

Our equation is

We are going to solve this with the quadratic formula

Followed?
