\frac{2}{\left(x+2\right)\left(x+5\right)}+\frac{3}{\left(x-5\right)\left(x+5\right)}
Ffactora x^{2}+7x+10. Ffactora x^{2}-25.
\frac{2\left(x-5\right)}{\left(x-5\right)\left(x+2\right)\left(x+5\right)}+\frac{3\left(x+2\right)}{\left(x-5\right)\left(x+2\right)\left(x+5\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin \left(x+2\right)\left(x+5\right) a \left(x-5\right)\left(x+5\right) yw \left(x-5\right)\left(x+2\right)\left(x+5\right). Lluoswch \frac{2}{\left(x+2\right)\left(x+5\right)} â \frac{x-5}{x-5}. Lluoswch \frac{3}{\left(x-5\right)\left(x+5\right)} â \frac{x+2}{x+2}.
\frac{2\left(x-5\right)+3\left(x+2\right)}{\left(x-5\right)\left(x+2\right)\left(x+5\right)}
Gan fod gan \frac{2\left(x-5\right)}{\left(x-5\right)\left(x+2\right)\left(x+5\right)} a \frac{3\left(x+2\right)}{\left(x-5\right)\left(x+2\right)\left(x+5\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{2x-10+3x+6}{\left(x-5\right)\left(x+2\right)\left(x+5\right)}
Gwnewch y gwaith lluosi yn 2\left(x-5\right)+3\left(x+2\right).
\frac{5x-4}{\left(x-5\right)\left(x+2\right)\left(x+5\right)}
Cyfuno termau tebyg yn 2x-10+3x+6.
\frac{5x-4}{x^{3}+2x^{2}-25x-50}
Ehangu \left(x-5\right)\left(x+2\right)\left(x+5\right).
