each other...ok right?
yes, where the two equations cross, I will need to to plug into the bounds of green's theorem

we want to know where y = y really
and y = 4x and y = 2x^2
so..... 4x = 2x^2 when?
0 = 2x^2 -4x
0 = 2x(x-2) ; recall that any number times zero will equal zero.
so either (0)(x-2) = 0
or; 2x(x-2) = 0
2x=0 when x = 0
x-2 = 0 when x = 2
green has a theorum?
....im pretty sure your smart enough to catch that :) 2x(0 = 0 is what I meant lol
thanks, I hate forgetting basic factoring and algebra
it takes practice, it like typing....you can be a pro at it and still mess it up lol
yup thanks, I've been spoiled by a calc and my professor refuses us to ever use on in class
