Use the intermediate value
Not sure that is why I asked :)
Use the intermediate value
Use the intermediate value theorem to show that the polynomial function has a zero in the given interval. f(x)=9x^4-3x^2+5x-1;[0,1]

Form a polynomial f(x) with real coefficents having the given degree and zeros degree 5; zeros: 5; -i; -9 +i f(x)=a
Using the remainder
use the remainder theorem to find the remainder when f(x) is divided by x - 3. Then use the factor theorem to determine whether x-3 is a factor of f(x) f(x)=2x^3-10x^2+11x+12
