Question

Find the discriminant 7x^2-5x+1=0​

Answer 1

Answer:

Therefore,

$Discriminant=-3$

Step-by-step 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

$Discriminant=(-5)^{2}-4\times 7\times 1\\Discriminant=25-28\\Discriminant=-3$

Therefore,

$Discriminant=-3$
