Use the discriminant to find the number of real solutions of the equation 3x^2 – 5x 4 = 0

So,

I'm assuming you mean 3x^2 - 5x + 4 = 0.

The discriminant is as follows:


Substitute the appropriate numbers.


Simplify.

25 - 12(4)
25 - 48
-23

As this is a negative number, there will be two complex roots.

Since complex roots are not real numbers, there will be zero real roots.

221,500 is the answer
