\frac{\left(2y-1\right)\left(y+7\right)}{\left(y^{2}-49\right)\left(1-2y\right)}
Whakawehe \frac{2y-1}{y^{2}-49} ki te \frac{1-2y}{y+7} mā te whakarea \frac{2y-1}{y^{2}-49} ki te tau huripoki o \frac{1-2y}{y+7}.
\frac{-\left(y+7\right)\left(-2y+1\right)}{\left(-2y+1\right)\left(y^{2}-49\right)}
Unuhia te tohu tōraro i roto o 2y-1.
\frac{-\left(y+7\right)}{y^{2}-49}
Me whakakore tahi te -2y+1 i te taurunga me te tauraro.
\frac{-\left(y+7\right)}{\left(y-7\right)\left(y+7\right)}
Me whakatauwehe ngā kīanga kāore anō i whakatauwehea.
\frac{-1}{y-7}
Me whakakore tahi te y+7 i te taurunga me te tauraro.
