Question

Discriminant of x^2 -6x +4=0?

Answer 1

you need the value of x

Answer 2

Wow ok that's confusing.

Answer 3

To find the discriminant the formula is \[b ^{2}-4ac\]

Your A would be 1 because coefficient of x^2 is 1, B is -6, and C is 4

Plug that into the formula you get

\[(-6)^{2}-4(1)(4)\]
36-16
=20
