Name each of the polar curves: a)
r=4costheta
b)
r=3+3 sintheta
c)
r=sin 3theta
d)
r = sin 4theta

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
