Write a polynomial function f of least degree that has rational coefficients, a leading coefficient of 1, and the given zeros. 3, 4+2i, 1+(sqrt)7 the answer is supposed to be: f(x)=x(^5)-13x(^4)+60x(^3)-82x(^2)-144x+360 what am i doing wrong?

Is (0,0) a to ? ys x2 - 4 y> 2x-1

Which angle is the smallest? also give me an explanation so i can complete it to other questions as well, : )
