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

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

Evalwa

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

Passi tas-Soluzzjonijiet

Ikkombina 4y u 9y biex tikseb 13y.

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

Ikkombina 13y u \frac{4}{5}y biex tikseb \frac{69}{5}y.

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

Ikkombina \frac{2}{5}y^{2} u -y^{2} biex tikseb -\frac{3}{5}y^{2}.

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

Fattur
