2-k=5x^{2}-3x
Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.
-k=5x^{2}-3x-2
Tynnu 2 o'r ddwy ochr.
\frac{-k}{-1}=\frac{\left(x-1\right)\left(5x+2\right)}{-1}
Rhannu’r ddwy ochr â -1.
k=\frac{\left(x-1\right)\left(5x+2\right)}{-1}
Mae rhannu â -1 yn dad-wneud lluosi â -1.
k=-\left(x-1\right)\left(5x+2\right)
Rhannwch \left(-1+x\right)\left(2+5x\right) â -1.
