Find the values of the discriminant for ...

Find the values of the discriminant for the following equadratic equations :
`x^(2)+7x-1=0`

Text Solution

Verified by Experts

The correct Answer is:
`Delta=53`
Comparing `x^(2)+7x-1=0` with `ax^(2)+bx+c=0`
`a=1,b=7,c=-1`
`Delta=b^(2)-4ac=(7)^(2)-4(1)(-1)`
=49+4=53
