Whakaoti i te 4y+2/5y^2+9y+4/5y-y^2

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

Aromātai

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

Ngā Upane Otinga

Pahekotia te 4y me 9y, ka 13y.

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

Pahekotia te 13y me \frac{4}{5}y, ka \frac{69}{5}y.

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

Pahekotia te \frac{2}{5}y^{2} me -y^{2}, ka -\frac{3}{5}y^{2}.

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

Tauwehe

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

Ngā Upane Otinga

Tauwehea te \frac{1}{5}.

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

Whakaarohia te 20y+2y^{2}+45y+4y-5y^{2}. Tauwehea te y.

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

Whakaarohia te 20+2y+45+4-5y. Whakarea ka paheko i ngā kīanga tau ōrite.

$$-3y+69$$

Whakaarohia te -3y+69. Tauwehea te 3.

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

Me tuhi anō te kīanga whakatauwehe katoa.

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