ok i need to find a polynomial function given these zeros: -5, -5,1+(rad 3)i... my teacher said its gotta have an x^4 in it but theres only 3 zeros 0.o...
the fourth zero would be 1-(rad 3)i b/c imaginary roots always come in + - pairs. As for how to solve the rest, just put them in an equation and multiply them. y=(x+5)(x+5)(x-(1-(rad 3)i))(x-(1+(rad 3)i)) I'm not gonna multiply them out b/c that would take forever to type, but if you have a pencil and paper it shouldn't be too difficult. Just remember not to screw up the signs. Sorry about the parentheses mess, its the only way I could think of writing them.
