Best ResponseYou've already chosen the best response.0Or graph it. This does not look nice to factor.

Best ResponseYou've already chosen the best response.0Isnt there a step in between,, like : 9x^26x3=0

Best ResponseYou've already chosen the best response.0How did you propose graphing it without the factors, anyway, polpak?

Best ResponseYou've already chosen the best response.0Let me start over... shoudnt it be 9x(3)7x2 the zeros will be 1, 2/3, 1/3

Best ResponseYou've already chosen the best response.0And MDot, the first step is noting that f(1) = 0 (by inspection), so (x1) is a factor. Then youjust go normally.

Best ResponseYou've already chosen the best response.0And get to the above thing, probably with (x1)(quad) which becomes the thing above

Best ResponseYou've already chosen the best response.0ok so, (0)= 2 (+/ 1), (+/ 2)

Best ResponseYou've already chosen the best response.0and q is a factor of a(n)= 9 right?

Best ResponseYou've already chosen the best response.0I have no idea what you were talking about, I was just giving you the steps polpak (presumably) went through, when you asked wasn't there something in the middle. your zeros 1, 2/3, 1/3 before were right...
