Hey, this is summer work and i forgot all about these. the equation is:
f(x)=x^3-(11/3)x^2+(5/3)x+1
I have to find all the real zeros. So far ive multiplied by 3 to make it
f(x)=3x^3-11x^2+5x+1
Am I right? How do i finish this? thanks guys

Here are some posts from the forum that tackle problems like these. some have very detailed explanations. so if you don't get it from one, look at the others. if you are still lost, you can ask questions. but only after you have gone through all the threads and tried to grasp the concept. that's the best way to go
