Question

Can you please help me, this assignment is due tonight.

Answer 1

Find all rational zeros of the polynomial. (Enter your answers as a comma-separated list. If a zero has multiplicity greater than one, only enter the root once.)
\[P(x)=10x^4−13x^3−198x^2+61x+20\]

Answer 2

Do you know synthetic division?

Answer 3

Yes I do, but during this problem you get too many equations you must work out. I know there is a way to have less problems to work with. Such as the upper and lower bounds theorem. That is where I am confused on, I don't really get these theorems.
