I’m supposed to find the roots of $3y^2z – z^3$ by finding $y$. I’m thinking this is going to be a complex root because $-z^3$ is its negative, and because $3z^2y^2$ is the product of the roots and because $y^3$ is the negative of the sum of the roots. However, I get that the roots are $\pm\sqrt{2}$, which is real, and thus the given answer is wrong. Where did I go wrong? A: Yes, the given answer is wrong. You reasoned that the roots are $\pm\sqrt{2}$, so the sum is $2+2\sqrt{2}$ and the product is $2\sqrt{2}$. However, you should have reasoned that the roots are $\pm\sqrt{2}i$. In fact, it’s usually easier to recognize a complex square root when written in standard form, $x+iy$. This gives you the sum and product of $x^3$ and $y^3$: $x^3+y^3 = 2(x^3)$, so $x^3 = 2y^3$, and the sum and product of the roots are $x+iy$ and $x-iy$, so $x^2-y^2=(x+iy)(x-iy)$, whence \$x^
