Question

Find the discriminant 7x^2-5x+1=0​

Answer 1

Therefore,

`Discriminant=-3`

Explanation:

Given:

`7x^(2)-5x+1=0`

To Find:

Discriminant = ?

Solution:

For a Quadratic Equation ax²+bx+c=0

The Discriminant is given as

`Discriminant=b^(2)-4ac`

On comparing we get

`a=7\\b=-5\\c=1`

Substituting the values we get

`Discriminant=(-5)^(2)-4* 7* 1\\Discriminant=25-28\\Discriminant=-3`

Therefore,

`Discriminant=-3`
