(2w^2-14)^2 eching

$$( 2 w ^ { 2 } - 14 ) ^ { 2 }$$

Baholash

$$4\left(w^{2}-7\right)^{2}$$

Yechim qadamlari

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(2w^{2}-14\right)^{2} kengaytirilishi uchun ishlating.

$$4\left(w^{2}\right)^{2}-56w^{2}+196$$

Daraja ko‘rsatkichini boshqa ko‘rsatkichga oshirish uchun, darajalarini ko‘paytiring. 2 va 2 ni ko‘paytirib, 4 ni oling.

$$4w^{4}-56w^{2}+196$$
