Best ResponseYou've already chosen the best response.1The function is this right? \[\Large f(x) = \frac{x^2+14x+24}{3x^211}\]

Best ResponseYou've already chosen the best response.1First replace f(x) with 0. Then multiply both sides by \(\Large 3x^211\) \[\Large f(x) = \frac{x^2+14x+24}{3x^211}\] \[\Large 0 = \frac{x^2+14x+24}{3x^211}\] \[\Large 0*(3x^211) = \frac{x^2+14x+24}{3x^211}*(3x^211)\] \[\Large 0 = x^2+14x+24\] \[\Large x^2+14x+24=0\] Do you see how to solve from here?

Best ResponseYou've already chosen the best response.1so if (x+2)(x+12) = 0 then either x+2 = 0 or x+12 = 0 solve each equation for x to get your 2 answers
