3x-3+\frac{1}{x+3}+1-\frac{3}{2x+1}
Cyfuno 2x a x i gael 3x.
3x-2+\frac{1}{x+3}-\frac{3}{2x+1}
Adio -3 a 1 i gael -2.
\frac{\left(3x-2\right)\left(x+3\right)}{x+3}+\frac{1}{x+3}-\frac{3}{2x+1}
I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch 3x-2 â \frac{x+3}{x+3}.
\frac{\left(3x-2\right)\left(x+3\right)+1}{x+3}-\frac{3}{2x+1}
Gan fod gan \frac{\left(3x-2\right)\left(x+3\right)}{x+3} a \frac{1}{x+3} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.
\frac{3x^{2}+9x-2x-6+1}{x+3}-\frac{3}{2x+1}
Gwnewch y gwaith lluosi yn \left(3x-2\right)\left(x+3\right)+1.
\frac{3x^{2}+7x-5}{x+3}-\frac{3}{2x+1}
