Question

find all the zeros of the polynomial 2x^4-9x^3+5x^2+3x-1 if two of it's zeros are (2+√3)and (2-√3)

Answer 1

We know that if  is a zero of a polynomial, then  is a factor of .

Since, and  are zeros of .

Therefore 





is a factor of .Now, we divide  by  to find the other zeros of .



By using division algorithm we have
