im doing this thing and i need to know how to add square roots in their simplist forms together eg....

Sqrt(7)+Sqrt(7) any one wanna help me out on this one?

fuuuuuuu.... damn it i cant believe i forgot now how do i do -6 times i (sqrt) (7)

btw thanks mosier


edit: nvm i gave up on this equasion thing.

Ssshhhhh. I used this site the other night. Works well for most things, hope it can help you out.

holy FAUK! bookmarks tyvm deady...this is almost what i need im in algebra 2 though lets see if it knows what its doing =)

god damn damn it it doesnt support division and square roots which is basically all this thing im doing is =/

no this isnt hard its that i need it for this equasion


p(x)=x^3-2x^2+8x; 0, -1, 1+i sqrt(7), 1-i sqrt (7)
i just couldnt figure out the last two...

and i forgot how to do it.....
plug in those numbers and what not for x gets on my nerves

:| not everyone is good at math m0o. How about you try to help the kid instead of trying to prove, yet again, that you are intelligent.

Also I have no idea how to do this sort of stuff. I don't have one of the few jobs that requires me to though, and in highschool all I did was sleep.

Nope. Or read.

lol.... nice one...by the way thanks for the help and whatnot
