\frac{\left(2y-1\right)\left(y+7\right)}{\left(y^{2}-49\right)\left(1-2y\right)}

I-divide ang \frac{2y-1}{y^{2}-49} gamit ang \frac{1-2y}{y+7} sa pamamagitan ng pagmu-multiply sa \frac{2y-1}{y^{2}-49} gamit ang reciprocal ng \frac{1-2y}{y+7}.

\frac{-\left(y+7\right)\left(-2y+1\right)}{\left(-2y+1\right)\left(y^{2}-49\right)}

I-extract ang negatibong sign sa 2y-1.

\frac{-\left(y+7\right)}{y^{2}-49}

I-cancel out ang -2y+1 sa parehong numerator at denominator.

\frac{-\left(y+7\right)}{\left(y-7\right)\left(y+7\right)}

I-factor ang mga expression na hindi pa na-factor.

\frac{-1}{y-7}

I-cancel out ang y+7 sa parehong numerator at denominator.
