y=7x^2-3
find the value of the discriminant
is there 2 real solution, 1 real solution, or no real solution

Respuesta :

Step-by-step explanation:

We have,

[tex]y=7x^2-3[/tex]

It is required to find the value of the discriminant. It is given by :

[tex]D=b^2-4ac[/tex]

Here, a = 7 b = 0 and c = -3

So,

[tex]D=(0)^2-4\times 7\times (-3)\\\\D=84[/tex]

The discriminant is positive here, it means that it has two distinct real number solutions.
