(x^2-1)^2 eching

$$( x ^ { 2 } - 1 ) ^ { 2 }$$

Kengaytirish

$$x^{4}-2x^{2}+1$$

Yechim qadamlari

\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(x^{2}-1\right)^{2} kengaytirilishi uchun ishlating.

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

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

$$x^{4}-2x^{2}+1$$
