Datrys 2-2/u+2/frac{1{u+2}+u/2}

$$\frac { 2 - \frac { 2 } { u + 2 } } { \frac { 1 } { u + 2 } + \frac { u } { 2 } }$$

Enrhifo

$$\frac{4\left(u+1\right)}{u^{2}+2u+2}$$

Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch 2 â \frac{u+2}{u+2}.

$$\frac{\frac{2\left(u+2\right)}{u+2}-\frac{2}{u+2}}{\frac{1}{u+2}+\frac{u}{2}}$$

Gan fod gan \frac{2\left(u+2\right)}{u+2} a \frac{2}{u+2} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{\frac{2\left(u+2\right)-2}{u+2}}{\frac{1}{u+2}+\frac{u}{2}}$$

Gwnewch y gwaith lluosi yn 2\left(u+2\right)-2.

Cyfuno termau tebyg yn 2u+4-2.

$$\frac{\frac{2u+2}{u+2}}{\frac{1}{u+2}+\frac{u}{2}}$$

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

$$\frac{\frac{2u+2}{u+2}}{\frac{2}{2\left(u+2\right)}+\frac{u\left(u+2\right)}{2\left(u+2\right)}}$$

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

$$\frac{\frac{2u+2}{u+2}}{\frac{2+u\left(u+2\right)}{2\left(u+2\right)}}$$

Gwnewch y gwaith lluosi yn 2+u\left(u+2\right).

$$\frac{\frac{2u+2}{u+2}}{\frac{2+u^{2}+2u}{2\left(u+2\right)}}$$

Rhannwch \frac{2u+2}{u+2} â \frac{2+u^{2}+2u}{2\left(u+2\right)} drwy luosi \frac{2u+2}{u+2} â chilydd \frac{2+u^{2}+2u}{2\left(u+2\right)}.

$$\frac{\left(2u+2\right)\times 2\left(u+2\right)}{\left(u+2\right)\left(2+u^{2}+2u\right)}$$

Canslo u+2 yn y rhifiadur a'r enwadur.

$$\frac{2\left(2u+2\right)}{u^{2}+2u+2}$$

Defnyddio’r briodwedd ddosbarthu i luosi 2 â 2u+2.
