(D)????

anonymous · Answer

wow people lol math is not working

parthkohli · Answer

First step: Substitute $4x - 4$ for $y$.
Second step: $x^2 - 3x + 2 = y\implies x^2 - 3x + 2 = 4x - 4$.
Third step: $(x^2 - 3x + 2)- (4x - 4) = 0$

Continue solving your quadratic equation.

anonymous · Answer

how did you do that ????????????

lgbasallote · Answer

we had this new recent invention called photoshop

kinggeorge · Answer

I believe it is mathematics. Since it is labeled as math here.

lgbasallote · Answer

it's so hard to figure out which one is photoshopped

parthkohli · Answer

No, I experimented. I went to James's profile... then went to "Questions Asked"... and then the URL looked like this: http://openstudy.com/users/85295james#/updates/50418313e4b0d97e4dc5adab I removed "/users/85295james", and got this URL: http://openstudy.com/updates/50418313e4b0d97e4dc5adab

parthkohli · Answer

Or wait... it just shows the name of the group you are viewing.

kinggeorge · Answer

On my screen, I'm seeing the same thing parth is. However, the reply is labeled as being in mathematics.

parthkohli · Answer

But never mind... it's not OS Feedback because this question is not in the list of open questions.
