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?
]]>Now, we will need
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
