    I don't even know where to start, teacher gave us this with no direction. Suppose the polynomial R(x)=a9x^9+a8x^8+...+a,x+a0 has real coefficients with a9 cannot equal 0. Suppose also that R(x)has the following zeros: 5, 6, 5+5i.

    State the number of positive real zeros, negative real zeros, and imaginary zeros for g(x)= 9x3 -7x2+10x-4. Since there were 3 sign changes I have 3 positive real zeros. For g(-x)= I have -9x3-7x2-10x-4. There were no sign changes
