Here's the question you clicked on:

How do you find all the zeros of the function: f(x)=x^4-x^3+2x^2-4x-8
can you show me how to factor this problem
factored (x-2)*(x+1)*(x^2+4) ^ notice here you have to take negative sqrt of a the number so it is 2 imaginaries. {x = 2}, {x = -1}, {x = 2*I}, {x = -2*I}
Oh okay http://answers.yahoo.com/question/index?qid=20091115111403AAnQ7Zk I see what you did there :) Gracias!!!!
