Datrys 9y/4y+5+8y^2/6y+5=

$$\frac { 9 y } { 4 y + 5 } + \frac { 8 y ^ { 2 } } { 6 y + 5 } =$$

Enrhifo

$$\frac{y\left(32y^{2}+94y+45\right)}{\left(4y+5\right)\left(6y+5\right)}$$

Camau Ateb Byr

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluosrif lleiaf cyffredin 4y+5 a 6y+5 yw \left(4y+5\right)\left(6y+5\right). Lluoswch \frac{9y}{4y+5} â \frac{6y+5}{6y+5}. Lluoswch \frac{8y^{2}}{6y+5} â \frac{4y+5}{4y+5}.

$$\frac{9y\left(6y+5\right)}{\left(4y+5\right)\left(6y+5\right)}+\frac{8y^{2}\left(4y+5\right)}{\left(4y+5\right)\left(6y+5\right)}$$

Gan fod gan \frac{9y\left(6y+5\right)}{\left(4y+5\right)\left(6y+5\right)} a \frac{8y^{2}\left(4y+5\right)}{\left(4y+5\right)\left(6y+5\right)} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{9y\left(6y+5\right)+8y^{2}\left(4y+5\right)}{\left(4y+5\right)\left(6y+5\right)}$$

Gwnewch y gwaith lluosi yn 9y\left(6y+5\right)+8y^{2}\left(4y+5\right).

$$\frac{54y^{2}+45y+32y^{3}+40y^{2}}{\left(4y+5\right)\left(6y+5\right)}$$

Cyfuno termau tebyg yn 54y^{2}+45y+32y^{3}+40y^{2}.

$$\frac{94y^{2}+45y+32y^{3}}{\left(4y+5\right)\left(6y+5\right)}$$

Ehangu \left(4y+5\right)\left(6y+5\right).

$$\frac{94y^{2}+45y+32y^{3}}{24y^{2}+50y+25}$$

Ffactor

$$\frac{32y\left(y-\frac{-\sqrt{769}-47}{32}\right)\left(y-\frac{\sqrt{769}-47}{32}\right)}{\left(4y+5\right)\left(6y+5\right)}$$
