Datrys 7m^4/7m+2+3m^2/m+4=

$$\frac { 7 m ^ { 4 } } { 7 m + 2 } + \frac { 3 m ^ { 2 } } { m + 4 } =$$

Enrhifo

$$\frac{m^{2}\left(7m^{3}+28m^{2}+21m+6\right)}{\left(m+4\right)\left(7m+2\right)}$$

Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin 7m+2 a m+4 yw \left(m+4\right)\left(7m+2\right). Lluoswch \frac{7m^{4}}{7m+2} â \frac{m+4}{m+4}. Lluoswch \frac{3m^{2}}{m+4} â \frac{7m+2}{7m+2}.

$$\frac{7m^{4}\left(m+4\right)}{\left(m+4\right)\left(7m+2\right)}+\frac{3m^{2}\left(7m+2\right)}{\left(m+4\right)\left(7m+2\right)}$$

Gan fod gan \frac{7m^{4}\left(m+4\right)}{\left(m+4\right)\left(7m+2\right)} a \frac{3m^{2}\left(7m+2\right)}{\left(m+4\right)\left(7m+2\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{7m^{4}\left(m+4\right)+3m^{2}\left(7m+2\right)}{\left(m+4\right)\left(7m+2\right)}$$

Gwnewch y gwaith lluosi yn 7m^{4}\left(m+4\right)+3m^{2}\left(7m+2\right).

$$\frac{7m^{5}+28m^{4}+21m^{3}+6m^{2}}{\left(m+4\right)\left(7m+2\right)}$$

Ehangu \left(m+4\right)\left(7m+2\right).

$$\frac{7m^{5}+28m^{4}+21m^{3}+6m^{2}}{7m^{2}+30m+8}$$

Ffactor

$$\frac{m^{2}\left(7m^{3}+28m^{2}+21m+6\right)}{\left(m+4\right)\left(7m+2\right)}$$
