For the polynomial below, list each real zero and its multiplicity. f(x) = (x + 1/4)^4 (x^2 + 1)^5 I don't know where to start on this! |

x=-1/4, multiplicity 4. the other factor yields only imaginary zeros. You set each factor equal to zero and then solve for x. For the first factor, (x+1/4)^4=0, this is really four factors: x+1/4=0. for the second factor to the power 5, that is really 5 factors: x^2+1=0 so, x^2=-1 which has imaginary zeros. ---------------------------------------- Principal Skinner |
