Question

Simplify the following rational function: 2x-1/1-2x

Answer 1

\[\large \frac{2x-1}{1-2x}\]


\[\large \frac{2x-1}{-1(-1+2x)}\]


\[\large \frac{2x-1}{-1(2x-1)}\]


\[\large \frac{\cancel{2x-1}}{-1\cancel{(2x-1)}}\]


\[\large \frac{1}{-1}\]


\[\large -1\]
So \[\large \frac{2x-1}{1-2x}=-1\]
