\frac{\left(x^{2}+4x-5\right)\times 4x}{2x^{2}\left(x-1\right)}
Divide \frac{x^{2}+4x-5}{2x^{2}} by \frac{x-1}{4x} by multiplying \frac{x^{2}+4x-5}{2x^{2}} by the reciprocal of \frac{x-1}{4x}.
\frac{2\left(x^{2}+4x-5\right)}{x\left(x-1\right)}
Cancel out 2x in both numerator and denominator.
\frac{2\left(x-1\right)\left(x+5\right)}{x\left(x-1\right)}
Factor the expressions that are not already factored.
\frac{2\left(x+5\right)}{x}
Cancel out x-1 in both numerator and denominator.
\frac{2x+10}{x}
Expand the expression.
