Issolvi 1-1-2y^2/1-y+y

$$1 - \frac { 1 - 2 y ^ { 2 } } { 1 - y } + y$$

Evalwa

$$\frac{y^{2}}{1-y}$$

Passi Qosra tas-Soluzzjonijiet

Biex iżżid jew tnaqqas l-espressjonijiet, espandihom biex id-denominaturi tagħhom ikunu l-istess. Immultiplika 1+y b'\frac{1-y}{1-y}.

$$\frac{\left(1+y\right)\left(1-y\right)}{1-y}-\frac{1-2y^{2}}{1-y}$$

Billi \frac{\left(1+y\right)\left(1-y\right)}{1-y} u \frac{1-2y^{2}}{1-y} għandhom l-istess denominatur, naqqashom billi tnaqqas in-numeraturi tagħhom.

$$\frac{\left(1+y\right)\left(1-y\right)-\left(1-2y^{2}\right)}{1-y}$$

Agħmel il-multiplikazzjonijiet fi \left(1+y\right)\left(1-y\right)-\left(1-2y^{2}\right).
