\frac{10}{\left(x+3\right)^{2}}+\frac{2}{x+3}
Ffactora x^{2}+6x+9.
\frac{10}{\left(x+3\right)^{2}}+\frac{2\left(x+3\right)}{\left(x+3\right)^{2}}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \left(x+3\right)^{2} a x+3 yw \left(x+3\right)^{2}. Lluoswch \frac{2}{x+3} â \frac{x+3}{x+3}.
\frac{10+2\left(x+3\right)}{\left(x+3\right)^{2}}
Gan fod gan \frac{10}{\left(x+3\right)^{2}} a \frac{2\left(x+3\right)}{\left(x+3\right)^{2}} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{10+2x+6}{\left(x+3\right)^{2}}
Gwnewch y gwaith lluosi yn 10+2\left(x+3\right).
\frac{16+2x}{\left(x+3\right)^{2}}
Cyfuno termau tebyg yn 10+2x+6.
\frac{16+2x}{x^{2}+6x+9}
Ehangu \left(x+3\right)^{2}.
