Best ResponseYou've already chosen the best response.0use the quadratic formula after getting all terms on one side 4x2+8x+1 so a=4, b=8, and c=1 plug into qf

Best ResponseYou've already chosen the best response.0one last question.. how did you know that the qf was necessary? just in case other problems like these come up. how can i decipher whether i need it or not.

Best ResponseYou've already chosen the best response.0if you can't solve the quadratic equation by factoring then your other options are by completing the square or the quadratic formula

Best ResponseYou've already chosen the best response.0not sure if youre still there, but one thing my friend didnt understand was how it was simplified to the final answer. isnt the 4 outside the square root technically tied to it and you can't really simplify it?

Best ResponseYou've already chosen the best response.0The simplification was valid. The 48 inside the radical was factored to 16 and 3, the square root of 16 was accomplished by moving the 4 outside of the radical leaving only the square root of 3 within the radical.
