solve it first and win.
keep it rational.

x^4 + x^3 + 7x^2 - x + 6

Are we assuming this is equal to zero? do we graph it? get its derivative? what?

The roots are

x \approx -0.670517+2.46785 i

x \approx -0.670517-2.46785 i

x \approx 0.170517-0.942534 i

x \approx 0.170517+0.942534 i


according to WolframAlpha. No reals, let alone rationals.
