Question

What is the value of the discriminant in f(x)=6x ​2 ​​ +10x−1?

Answer 1

`124`

Explanation:

The discriminant is equal to `b^2-4ac`. We just need to find our values for `a, b` and `c` and plug them into our expression for the discriminant.

This quadratic is in standard form, `ax^2+bx+c`. We know the following:

`a=6`
`b=10`
`c=-1`

Now we can plug the values in:

`10^2-4(6)(-1)= 100-24(-1)= 100+24=124`

The discriminant is `124`
