Factor f(x)= x^4 - x^3 -7x^2+13x-6 completely. use the fundamental theorem of algebra fo determine the number of complex roots. possible rational roots are: since a is and n is the graph will go to as x approaches ∞ , and as x approaches - ∞ . the y intercept is the x intercepts are: describe the multiplicity if each root: use synthetic division to check each possible root: you dont have to do all of ! but plz show me how to solve ! i am having a really hard time trying to get an answer for this, and cant find much online to guide me.
