2-k=5x^{2}-3x
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
-k=5x^{2}-3x-2
Ikkala tarafdan 2 ni ayirish.
\frac{-k}{-1}=\frac{\left(x-1\right)\left(5x+2\right)}{-1}
Ikki tarafini -1 ga bo‘ling.
k=\frac{\left(x-1\right)\left(5x+2\right)}{-1}
-1 ga bo'lish -1 ga ko'paytirishni bekor qiladi.
k=-\left(x-1\right)\left(5x+2\right)
\left(-1+x\right)\left(2+5x\right) ni -1 ga bo'lish.
