The equation has 2 real roots

How to determine the number of real roots?

The equation is given as:

[tex]y = 3x^2 + 12x - 12[/tex]

Calculate the determinant using

d = b^2 - 4ac

So, we have:

d = 12^2 - 4 * 3 * (-12)

Evaluate

d = 288

Because d > 0

i.e. 288 is greater than 0

Then it means that the equation has 2 real roots
