Separate a polynomial as a product of 2 polynomials

2 次查看(过去 30 天)
I have random: x^3-3*x^2+x-3. I need to make it (x+-number)*(x+-number). A product of 2 polynomials == multiplying each other. Can you help <3 Fresh blood here :)

Basic math here. What do you know about the roots of a polynomial? What does that tell you? What can you do with the roots, IF you knew those roots? How does that help you to factor the polynomial?
Finally, what tools are available in MATLAB to compute the roots of a polynomial? (Hint: roots, solve, vpasolve) You can even use eig, if you know how to compute a companion matrix, and what that tells you. (Hint: compan)
But, sorry, I won't do your homework.
