Question

HELP!!! Find the discriminant
5x^2-6x+2=0

I say the answer is -76 but I'm getting it marked wrong. Please help

Answer 1

first identify your a, b, and c values

Answer 2

I did. I got -76 which is the incorrect answer
A is 5
B is -6
C is 2

Answer 3

What am I getting wrong

Answer 4

A is 5
B is -6
C is 2

Discriminant: b^2 -4*a*c

(-6)^2 - 4*(5)*(2) is not equal to -76

I suspect that somebody cranked out (-6)^2 as -36 which is INcorrect.

Try again.

Answer 5

No I actually used -4 which was wrong. I got the answer by using 4. Thx
