Solve for f
f=x-7+\frac{10}{x}
x\neq 0
Solve for x (complex solution)
x=\frac{-\sqrt{f^{2}+14f+9}+f+7}{2}
x=\frac{\sqrt{f^{2}+14f+9}+f+7}{2}
Solve for x
x=\frac{-\sqrt{f^{2}+14f+9}+f+7}{2}
x=\frac{\sqrt{f^{2}+14f+9}+f+7}{2}\text{, }f\geq 2\sqrt{10}-7\text{ or }f\leq -2\sqrt{10}-7

xf=x^{2}-7x+10
The equation is in standard form.
\frac{xf}{x}=\frac{\left(x-5\right)\left(x-2\right)}{x}
Divide both sides by x.
f=\frac{\left(x-5\right)\left(x-2\right)}{x}
Dividing by x undoes the multiplication by x.
f=x-7+\frac{10}{x}
Divide \left(-5+x\right)\left(-2+x\right) by x.
