In my textbook, there's a question I came across:

When you use graphing technology to factor a polynomial function, which type of factors are difficult to recognize from the graph?


I'm not entirely sure how I should answer this. When I graph a polynomial function to look for the zeros, the zeros are fairly simple to identify (that's how I understood the question- when you're "factoring a polynomial function using graphing technology," don't you look for the zeros of the function?). There's no answer key for this question.


How would you answer this?


Thank you! :)

For polynomials with repeated roots it can be difficult to identify all the factors.  e.g.  y = x2 - 4x + 4   (which is y = (x-2)2 ).
