Datrys 6/x+3-2/x+5

$$\frac { 6 } { x + 3 } - \frac { 2 } { x + 5 }$$

Enrhifo

$$\frac{4\left(x+6\right)}{\left(x+3\right)\left(x+5\right)}$$

Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin x+3 a x+5 yw \left(x+3\right)\left(x+5\right). Lluoswch \frac{6}{x+3} â \frac{x+5}{x+5}. Lluoswch \frac{2}{x+5} â \frac{x+3}{x+3}.

$$\frac{6\left(x+5\right)}{\left(x+3\right)\left(x+5\right)}-\frac{2\left(x+3\right)}{\left(x+3\right)\left(x+5\right)}$$

Gan fod gan \frac{6\left(x+5\right)}{\left(x+3\right)\left(x+5\right)} a \frac{2\left(x+3\right)}{\left(x+3\right)\left(x+5\right)} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{6\left(x+5\right)-2\left(x+3\right)}{\left(x+3\right)\left(x+5\right)}$$

Gwnewch y gwaith lluosi yn 6\left(x+5\right)-2\left(x+3\right).

$$\frac{6x+30-2x-6}{\left(x+3\right)\left(x+5\right)}$$

Cyfuno termau tebyg yn 6x+30-2x-6.

$$\frac{4x+24}{\left(x+3\right)\left(x+5\right)}$$

Ehangu \left(x+3\right)\left(x+5\right).

$$\frac{4x+24}{x^{2}+8x+15}$$

Ffactor

$$\frac{4\left(x+6\right)}{\left(x+3\right)\left(x+5\right)}$$
