fx\left(x+1\right)=x+1-2
Whakareatia ngā taha e rua o te whārite ki te x+1.
fx^{2}+fx=x+1-2
Whakamahia te āhuatanga tohatoha hei whakarea te fx ki te x+1.
fx^{2}+fx=x-1
Tangohia te 2 i te 1, ka -1.
\left(x^{2}+x\right)f=x-1
Pahekotia ngā kīanga tau katoa e whai ana i te f.
\frac{\left(x^{2}+x\right)f}{x^{2}+x}=\frac{x-1}{x^{2}+x}
Whakawehea ngā taha e rua ki te x^{2}+x.
f=\frac{x-1}{x^{2}+x}
Mā te whakawehe ki te x^{2}+x ka wetekia te whakareanga ki te x^{2}+x.
f=\frac{x-1}{x\left(x+1\right)}
Whakawehe x-1 ki te x^{2}+x.
