f(x)=(4(x^3)+38(x^2)+44x-20)/(20+12x+x^2), to find when this is equal to 0 (or if it ever does) and what method is used to determine these properties

How would you go about solving (4(x^3)+38(x^2)+44x-20)/(20+12x+x^2), without the use of a computer, further, what about functions which have more x components, with higher powers. Also what process do computers use to solve these.

Thank you very much (:

My question is, if a car is moving at speed V, and its front wheels are at an angle (theta), what is the relationship between the angle of the wheels relative to them being parallel with the car and the radius of the circle at which the car goes around. Thanks.
