Answer 3

please help!

Answer 4

it will be undefined when
\(\large \color{black}{\begin{align} \frac{ 3v^2+9 }{ v^2-2v-3 }=\infty\hspace{.33em}\\~\\
\frac{ 3v^2+9 }{ v^2-2v-3 }=\dfrac{1}{0}\hspace{.33em}\\~\\
\frac{ v^2-2v-3 }{ 3v^2+9 }=\dfrac{0}{1}\hspace{.33em}\\~\\
v^2-2v-3 =0
\end{align}}\)

solve the quadratic equation now

Answer 5

unidentified. means v^2-2v-3=0

Answer 6

solve for v

Answer 7

what would that value of v be when it is unidentified is what the computer is asking for

Answer 8

oh so i solve for v and that is the answer?

Answer 9

yes

Answer 10

make sure the spelling is correct whether it is undefined or unidentified.

Answer 11

-1 and 3

Answer 12

is that correct?

Answer 13

@AJ01 ?

Answer 14

he is offline. does anyone else know?

Answer 15

v2-2v-3=0
v^2-3v+v-3=0
v(v-3)+1(v-3)=0
(v+1)(v-3)=0
So
v=-1,3
