Ex: 3m^2+8m-4=3
Choices:
A)148 B)-47
C)112 D)-20

Answer 1

\[Discriminant = b^2-4 \times a \times c\]

Answer 2

\[3m^2+8m-4=3\]
\[3m^2+8m-7=0\]
a=3 , b=8 , c=-7

Answer 3

Now that you know what a, b, and c are equal to, plug it in the formula above.

Answer 4

Where did the 4 in the first equation come from?

Answer 5

4 is part of the quadratic formula, it's always there.

Answer 6
