Question

Find the Discriminant.
x^2-30x-64=0

Answer 1

The discriminant is defined as
$$\Large{ ax^2 +bx + c = 0
\\~\\ \Delta = b^2 - 4ac

}$$

Answer 2

\[y=2x^2−30x−64 \]
\[discriminant=b^2−4(a)(c)\]
\[(−30)2−4(2)(−64)=? \]

Answer 3

ax2+bx+c=0
diecriment D=sqr(b2-4ac)
put value and solve

Answer 4

-132?

Answer 5

not quite

Answer 6

(−30)^2−4(2)(−64)

Answer 7

oops sorry :/ must've made a typo... yeah ignore the 2 @yoda5657

Answer 8

(-30)^2 - 4(1)(-6 <---solve

Answer 9

I'm getting 1156.
