kx+k=-2x^{2}
Ikkala tarafdan 2x^{2} ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
\left(x+1\right)k=-2x^{2}
k'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(x+1\right)k}{x+1}=-\frac{2x^{2}}{x+1}
Ikki tarafini x+1 ga bo‘ling.
k=-\frac{2x^{2}}{x+1}
x+1 ga bo'lish x+1 ga ko'paytirishni bekor qiladi.
