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

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

Baholash

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

Yechim qadamlari

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

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

1+2y+y^{2} teskarisini topish uchun har birining teskarisini toping.

$$x^{2}-1-2y-y^{2}$$

Kengaytirish

$$x^{2}-y^{2}-2y-1$$
