Datrys 4y+2/5y^2+9y+4/5y-y^2

$$4 y + \frac { 2 } { 5 } y ^ { 2 } + 9 y + \frac { 4 } { 5 } y - y ^ { 2 }$$

Enrhifo

$$\frac{3y\left(23-y\right)}{5}$$

Camau Ateb

Cyfuno 4y a 9y i gael 13y.

$$13y+\frac{2}{5}y^{2}+\frac{4}{5}y-y^{2}$$

Cyfuno 13y a \frac{4}{5}y i gael \frac{69}{5}y.

$$\frac{69}{5}y+\frac{2}{5}y^{2}-y^{2}$$

Cyfuno \frac{2}{5}y^{2} a -y^{2} i gael -\frac{3}{5}y^{2}.

$$\frac{69}{5}y-\frac{3}{5}y^{2}$$

Ffactor

$$\frac{3y\left(23-y\right)}{5}$$

Camau Ateb

Ffactora allan \frac{1}{5}.

$$\frac{20y+2y^{2}+45y+4y-5y^{2}}{5}$$

Ystyriwch 20y+2y^{2}+45y+4y-5y^{2}. Ffactora allan y.

$$y\left(69-3y\right)$$

Ystyriwch 20+2y+45+4-5y. Lluosi a chyfuno termau sydd yr un fath.

$$-3y+69$$

Ystyriwch -3y+69. Ffactora allan 3.

$$3\left(-y+23\right)$$

Ailysgrifennwch y mynegiad cyfan wedi'i ffactorio.

$$\frac{3y\left(-y+23\right)}{5}$$
