9x^{2}-12x+4=9x^{2}-12x+4
\left(a-b\right)^{2}=a^{2}-2ab+b^{2} binom teoremasini \left(3x-2\right)^{2} kengaytirilishi uchun ishlating.
9x^{2}-12x+4-9x^{2}=-12x+4
Ikkala tarafdan 9x^{2} ni ayirish.
-12x+4=-12x+4
0 ni olish uchun 9x^{2} va -9x^{2} ni birlashtirish.
-12x+4+12x=4
12x ni ikki tarafga qo’shing.
4=4
0 ni olish uchun -12x va 12x ni birlashtirish.
\text{true}
4 va 4 ni taqqoslang.
x\in \mathrm{C}
Bu har qanday x uchun to‘g‘ri.
