The equation x3 + 3x2 + 5x + 15 = 0 has real and imaginary solution(s).

given equation:

let us factor it by making it into two groups.

gcf of first group is x^2 and second group 5.

factoring out common paranthesis (x+3), we get

setting each factor equal to 0. we get

x+3=0

x=-3

taking square root on both sides.

we get

x= +5i and x=-5i.

so, we got two imaginary roots -5i and 5i and one real root -3.

the correct answer is 1: 2
