2x^2 -x +4 / x^3 +4x Not that;

(2x^2 -x +4) / (x^3 +4x) but that.

%282x%5E2+-x+%2B4%29+%2F+%28x%5E3+%2B4x%29
The denominator is x%28x%5E2%2B4%29.

Look for a decomposition like
A%2Fx%2B%28Bx%2BC%29%2F%28x%5E2%2B4%29

Partial decomposition of %282x%5E2+-+x+%2B+4%29%2F%28x%5E3+%2B+4x%29: highlight_green%281%2Fx+-+1%2F%28x%5E2+%2B+4%29+%2B+x%2F%28x%5E2+%2B+4%29%29

You can do the check!!
