x^{2}+4x+4=x^{2}+4
\left(a+b\right)^{2}=a^{2}+2ab+b^{2} binom teoremasini \left(x+2\right)^{2} kengaytirilishi uchun ishlating.
x^{2}+4x+4-x^{2}=4
Ikkala tarafdan x^{2} ni ayirish.
4x+4=4
0 ni olish uchun x^{2} va -x^{2} ni birlashtirish.
4x=4-4
Ikkala tarafdan 4 ni ayirish.
4x=0
0 olish uchun 4 dan 4 ni ayirish.
x=0
Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. 4 0 ga teng bo‘lmasa, x 0 ga teng bo‘lishi kerak.
