Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
a-n=\left(n+2\right)^{2}
Tenglamaning ikkala taraf kvadratini chiqarish.
a-n-\left(-n\right)=\left(n+2\right)^{2}-\left(-n\right)
Tenglamaning ikkala tarafidan -n ni ayirish.
a=\left(n+2\right)^{2}-\left(-n\right)
O‘zidan -n ayirilsa 0 qoladi.
a=\left(n+2\right)^{2}+n
\left(n+2\right)^{2} dan -n ni ayirish.
