Question

Can anyone help me?

Answer 1

On this

Answer 2

you remember your quadratic formula?

Answer 3

Yea?

Answer 4

discriminant formula:
\[\Delta = b^2 - 4ac\]

Answer 5

yea its part of the quadratic formula

Answer 6

note that your quadratic equation is given to you :
\[-x^2 -12x + 4 = 0 \]
and it's written in the form:
\[ax^2 + bx + c = 0 \]
So identify your "a" , "b" and "c" values and then plug it into the discriminant formula:
\[\Delta = b^2 - 4ac\]

Answer 7

So the rules of the discriminant, \(\Delta\) :

\(\Delta \gt 0\) , 2 real roots

\(\Delta =0\) , 1 real root

\(\Delta \lt 0\) , 2 complex roots (with i)

Answer 8

Hmm a bit confusing but I think I got it, thanks everyone for the help ounce again!
