I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin a\left(a+b\right) a 2 yw 2a\left(a+b\right). Lluoswch \frac{1}{a\left(a+b\right)} â \frac{2}{2}. Lluoswch \frac{1}{2} â \frac{a\left(a+b\right)}{a\left(a+b\right)}.
\frac{2+a\left(a+b\right)}{2a\left(a+b\right)}
Gan fod gan \frac{2}{2a\left(a+b\right)} a \frac{a\left(a+b\right)}{2a\left(a+b\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{2+a^{2}+ab}{2a\left(a+b\right)}
Gwnewch y gwaith lluosi yn 2+a\left(a+b\right).
\frac{2+a^{2}+ab}{2a^{2}+2ab}
Ehangu 2a\left(a+b\right).
