This concept is about finding the zeroes and factoring for a 4th or 5th degree polynomial. My problem is f(x)=-35x^4+93x^3-42x^2-15x-1. Because it is a fourth degree polynomial, we know it will have four zeroes. This video explains each step needed to find all the zeroes.
Something you should remember when doing this video is to follow all the steps. Make sure you correctly use the Descartes Rule of Signs to help check your answers to see if you have found the right number of positive and negative zeroes. If needed, make sure you do use the quadratic formula. Radicals can be tricky, so make sure all your signs are correct.
