I don't think so because everything you change is just like making a choice and for each choice you make it creates a paralell universe and if you change time with the right amount of caution both paralells would be accessable but do you think there are consciequences for changinging time?

I do as science has proved it only time travel backwards is a little tricky.

Okay I have a math exam (mock) tomorrow.. and I was doing revision when I had this question, I've never really got how to do this type of question (how to put the 1/2 into the brackets)...

My guess is:
y= ½ (x-4) (x+2)
y= ½x²-2x-2 Even if this is right once I get to here I don't know how to put it back in brackets without endless guess & checking...

When I put the equation into my graphics calculator it has the (x-4)(x-2) part with the x-intercepts at 4 and -2 but- Yay! I just just figured out how it works for GRAPHS. My caclulator has got the vertex at -4.5, half of the 3².... duh...

Hmm.. so I know how the graph works but I really don't get the equation, so my question still stands, how do you do an equation like this?
y= ½ (x-4) (x+2)
