Ffactora x^{2}-36.
\frac{4x}{\left(x-6\right)\left(x+6\right)}+\frac{24\left(x+6\right)}{\left(x-6\right)\left(x+6\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \left(x-6\right)\left(x+6\right) a x-6 yw \left(x-6\right)\left(x+6\right). Lluoswch \frac{24}{x-6} â \frac{x+6}{x+6}.
\frac{4x+24\left(x+6\right)}{\left(x-6\right)\left(x+6\right)}
Gan fod gan \frac{4x}{\left(x-6\right)\left(x+6\right)} a \frac{24\left(x+6\right)}{\left(x-6\right)\left(x+6\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{4x+24x+144}{\left(x-6\right)\left(x+6\right)}
Gwnewch y gwaith lluosi yn 4x+24\left(x+6\right).
