Well once you plug x in
OpenStudy (anonymous):
\[4(-2)^2/-2\]
OpenStudy (anonymous):
sorry,
\[4(-2)^2/(-2)+4\]
OpenStudy (anonymous):
So you would get
\[4\times4/2\]
OpenStudy (vshiroky):
16/2 = 8

OpenStudy (astrophysics):
\[\frac{ 4x^2 }{ x+4 } = \frac{ 4(-2)^2 }{ (-2)+4 } = \frac{ 4(-2)(-2) }{ -2 } = 4(-2) = -8\]

Astrophysics
-2 + 4 doesn't equal -2

OpenStudy (astrophysics):
\[\frac{ 4x^2 }{ x+4 } = \frac{ 4(-2)^2 }{ (-2)+4 } = \frac{ 4(-2)(-2) }{ 2 } = \frac{ 16 }{ 2 } = 8\] there you go!
