Question

Y=7x^2-3

find the value of the discriminant
is there 2 real solution, 1 real solution, or no real solution

Answer 1

Explanation:

We have,

`y=7x^2-3`

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

`D=b^2-4ac`

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

So,

`D=(0)^2-4* 7* (-3)\\\\D=84`

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