help please
since it's a homework, you must have had some notes on the topic being questioned... correct?
yes but i dont understand it
the question you have has to do with cubic polynomials, does your notes mention anything like that?
im looking now hold on
no it only talks about roots
what does it say about roots?
okay so let's just say, roots are the solutions of a polynomial equation. when graphed, they are the x values of the points that the polynomial curve that cuts/touches the x-axis. a quadratic polynomial has 2 roots a cubic polynomial has 3 roots a quartic polynomial has 4 roots, etc
take a look at the pictures here to give u an idea https://www.google.com.gh/search?q=how+to+solve+polynomial+equations&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&sa=N&tab=wi&ei=kv7iUavNO_Sp7AackIHYAQ&biw=1366&bih=667&sei=UQDjUdKkMo-R7AaewIHgBQ#um=1&hl=en&tbm=isch&sa=1&q=cubic+polynomial+equations&oq=cubic+polynomial+equations&gs_l=img.3..0i24.6808.8907.2.10839.2.2.0.0.0.0.179.357.0j2.2.0...0.0.0..1c.1.17.img.3JH-dGkUqfA&bav=on.2,or.r_cp.r_qf.&bvm=bv.48705608,d.ZGU&fp=f1c3c314c009e9fa&biw=1366&bih=667
with how your question has been asked, it should be easy for you to see the answer without solving it, you have an idea how polynomials are now, find out how to go about solving them. each type of polynomial has a different way of approaching it though one technique for some polynomial can be employed to solve another type of polynomial. so read on the specific type of polynomial you want to deal with and how to solve them. i see in your screenshot that you have multiple types of polynomials :P so do yourself some good and do a little bit of reading :P hope i helped a bit though
