x+1+\frac{3x}{\left(x-3\right)\left(x+2\right)}
Ffactora x^{2}-x-6.
\frac{\left(x+1\right)\left(x-3\right)\left(x+2\right)}{\left(x-3\right)\left(x+2\right)}+\frac{3x}{\left(x-3\right)\left(x+2\right)}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch x+1 â \frac{\left(x-3\right)\left(x+2\right)}{\left(x-3\right)\left(x+2\right)}.
\frac{\left(x+1\right)\left(x-3\right)\left(x+2\right)+3x}{\left(x-3\right)\left(x+2\right)}
Gan fod gan \frac{\left(x+1\right)\left(x-3\right)\left(x+2\right)}{\left(x-3\right)\left(x+2\right)} a \frac{3x}{\left(x-3\right)\left(x+2\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{x^{3}-x^{2}-6x+x^{2}-x-6+3x}{\left(x-3\right)\left(x+2\right)}
Gwnewch y gwaith lluosi yn \left(x+1\right)\left(x-3\right)\left(x+2\right)+3x.
\frac{x^{3}-4x-6}{\left(x-3\right)\left(x+2\right)}
Cyfuno termau tebyg yn x^{3}-x^{2}-6x+x^{2}-x-6+3x.
\frac{x^{3}-4x-6}{x^{2}-x-6}
Ehangu \left(x-3\right)\left(x+2\right).
