What is the number of real solutions? –11x^2 = x + 11

Given the equation:

or we can write above equation as:

or

The general equation of quadratic formula for ; where a, b and c are constant;

Use Discriminant formula:

If , then there are 2 roots.

If D = 0, then there is only 1 root.

If D <0, then there are no real roots.

Now, from the given equation we have

a =11, b= 1 and c =11

Then, using discriminant formula we have;

⇒D<0 [ No real roots]

Therefore, for the given equation , there are no real solutions.
