Factor out a 2.
OpenStudy (anonymous):
im pretty sure its 4 but im not sure
OpenStudy (anonymous):
2(x^2 - 6xy - 16y^2)
OpenStudy (anonymous):
its not multiple choice
OpenStudy (anonymous):
And 4 is incorrect..factor \(\sf x^2 - 6xy - 16y^2\), can you do that?

yes it could with the -8 it makes sense
OpenStudy (anonymous):
anchor man. Is it REALLY you?!
OpenStudy (anonymous):
?
OpenStudy (anonymous):
what now?
OpenStudy (anonymous):
They already give you (x - 8y)..finish factoring \(\sf x^2 - 6xy - 16y^2\)

his picture
is the guy off of the movie anchor man
OpenStudy (anonymous):
by odens beard
OpenStudy (anonymous):
where did you get the 6 from
OpenStudy (anonymous):
We factored out a 2.
2x^2 / 2 = x^2
-12xy / 2 = -6xy
-32y^2 = -16y^2
OpenStudy (anonymous):
-32y^2 / 2*

so it would be 16
OpenStudy (anonymous):
16x^2

your confusing me now so its -8
OpenStudy (anonymous):
-8 * -8 = -16?
OpenStudy (anonymous):
no its 64 duh
OpenStudy (anonymous):
Yes, so -8 is incorrect.
Multiply what to -8 gives us -16?
OpenStudy (anonymous):
