Kua tāruatia ki te papatopenga
fx=x^{2}+3x-28\frac{\mathrm{d}}{\mathrm{d}x}(n)y_{1}
Whakareatia te 4 ki te 7, ka 28.
xf=x^{2}+3x
He hanga arowhānui tō te whārite.
\frac{xf}{x}=\frac{x\left(x+3\right)}{x}
Whakawehea ngā taha e rua ki te x.
f=\frac{x\left(x+3\right)}{x}
Mā te whakawehe ki te x ka wetekia te whakareanga ki te x.
f=x+3
Whakawehe x\left(3+x\right) ki te x.
fx=x^{2}+3x-28\frac{\mathrm{d}}{\mathrm{d}x}(n)y_{1}
Whakareatia te 4 ki te 7, ka 28.
