y^2(3-y)+3(1-y^2) eching

$$y ^ { 2 } ( 3 - y ) + 3 ( 1 - y ^ { 2 } )$$

Baholash

$$3-y^{3}$$

Yechim qadamlari

y^{2} ga 3-y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3y^{2}-y^{3}+3\left(1-y^{2}\right)$$

3 ga 1-y^{2} ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3y^{2}-y^{3}+3-3y^{2}$$

0 ni olish uchun 3y^{2} va -3y^{2} ni birlashtirish.

$$-y^{3}+3$$
