Best ResponseYou've already chosen the best response.1Okay. so now use 7/6 to find it. y = 3x^27x+6 y = 3(7/6)^2 7(7/6) + 6 solve.

Best ResponseYou've already chosen the best response.1hmm instead of 121/10 should i just leave it as 10.08 cuz i have to graph this afterward ?

Best ResponseYou've already chosen the best response.1but the way my teacher did it was to set y=0 and just add and divide stuff on left and right side...which is confusing but i suppose we can use quadratic aswell :)

Best ResponseYou've already chosen the best response.1Your teacher must have used the "completing the square" method. It's hella confusing. It confuses me too. :/

Best ResponseYou've already chosen the best response.1yeah thats what that was, completing the square lol.... ok i got y= 7+ sqrt(23)/6 and what's next ?

Best ResponseYou've already chosen the best response.1i dont think u can reduce it down or anything right? and u can't even square root a negative
