-Fx=3x^{7}+2x^{5}-3x^{2}+x-1
Subtract 1 from both sides.
\left(-x\right)F=3x^{7}+2x^{5}-3x^{2}+x-1
The equation is in standard form.
\frac{\left(-x\right)F}{-x}=\frac{3x^{7}+2x^{5}-3x^{2}+x-1}{-x}
Divide both sides by -x.
F=\frac{3x^{7}+2x^{5}-3x^{2}+x-1}{-x}
Dividing by -x undoes the multiplication by -x.
F=-3x^{6}-2x^{4}+3x-1+\frac{1}{x}
Divide 3x^{7}+2x^{5}-3x^{2}+x-1 by -x.
