Datrys 9m^2-1/3m^2-6mn+9m^2-6m+1/6m-12n

$$\frac { 9 m ^ { 2 } - 1 } { 3 m ^ { 2 } - 6 m n } + \frac { 9 m ^ { 2 } - 6 m + 1 } { 6 m - 12 n }$$

Enrhifo

$$\frac{\left(3m-1\right)\left(m+1\right)\left(3m+2\right)}{6m\left(m-2n\right)}$$

Camau Ateb Byr

Ffactora 3m^{2}-6mn. Ffactora 6m-12n.

$$\frac{9m^{2}-1}{3m\left(m-2n\right)}+\frac{9m^{2}-6m+1}{6\left(m-2n\right)}$$

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin 3m\left(m-2n\right) a 6\left(m-2n\right) yw 6m\left(m-2n\right). Lluoswch \frac{9m^{2}-1}{3m\left(m-2n\right)} â \frac{2}{2}. Lluoswch \frac{9m^{2}-6m+1}{6\left(m-2n\right)} â \frac{m}{m}.

$$\frac{2\left(9m^{2}-1\right)}{6m\left(m-2n\right)}+\frac{\left(9m^{2}-6m+1\right)m}{6m\left(m-2n\right)}$$

Gan fod gan \frac{2\left(9m^{2}-1\right)}{6m\left(m-2n\right)} a \frac{\left(9m^{2}-6m+1\right)m}{6m\left(m-2n\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{2\left(9m^{2}-1\right)+\left(9m^{2}-6m+1\right)m}{6m\left(m-2n\right)}$$

Gwnewch y gwaith lluosi yn 2\left(9m^{2}-1\right)+\left(9m^{2}-6m+1\right)m.
