Issolvi E(x)=[x^4+2x^3+x^2/(x+1)^2-9]:(3x-9)-x/3

$$E ( x ) = [ \frac { x ^ { 4 } + 2 x ^ { 3 } + x ^ { 2 } } { ( x + 1 ) ^ { 2 } } - 9 ] : ( 3 x - 9 ) - \frac { x } { 3 }$$

Passi Qosra tas-Soluzzjonijiet

Iffattura l-espressjonijiet li mhumiex diġà fatturati f'\frac{x^{4}+2x^{3}+x^{2}}{\left(x+1\right)^{2}}.

$$\frac{\frac{x^{2}\left(x+1\right)^{2}}{\left(x+1\right)^{2}}-9}{3x-9}-\frac{x}{3}$$

Annulla \left(x+1\right)^{2} fin-numeratur u d-denominatur.
