Math Problem - 2

[jeffeh]

( 2x-2 / x^2 )* (x^3 / 4x - 8)

so from here I expanded and cancelled out (x-1) in the first fraction

then combined the two to get

2x^3 / 4x^2-2

from here I'm not sure if the x^3 would cancel out the x^2 on the bottom?

Go to a goddamn tutor. One problem is pushing it, but two?

No you can't because of the -2

Just cross multiply, it's easier to do it that way...

Are you being serious? You need an equal sign to cross multiply.

Maybe they're trying to mislead him? I was honestly tempted to do so through a PM. lol

How would you feel if someone purposely mislead you when you asked for help in one of your EE classes?

I think your username is kinda funny. Carry on.

I refuse to do this problem because it's too easy.

Would it kill you to use parenthesis? (x^3 / 4x - 8) != (x^3 / (4x - 8))

anyway, you might want to redo your work...there's only one (x-1) term, so you can't cancel.
