This is not an equation, there's no equal sign.
=================
solve  3x² + x - 2 = 0 is a possibility.
solve  3x² + x - 2 = pi is another
solve  3x² + x - 2 = -10000000 is another.
----------------
You have to spec what's the polynomial is equal to.
Why the other tutors assumed zero (0) is a mystery.
