Reiziniet \frac{3}{4} ar -\frac{3}{4}, reizinot skaitītāju ar skaitītāju un saucēju ar saucēju.
\frac{1}{4}x^{2}-\frac{4}{9}y^{2}+y+\frac{-9}{16}
Veiciet reizināšanas darbības daļskaitlī \frac{3\left(-3\right)}{4\times 4}.
\frac{1}{4}x^{2}-\frac{4}{9}y^{2}+y-\frac{9}{16}
Daļskaitli \frac{-9}{16} var pārrakstīt kā -\frac{9}{16} , izvelkot negatīvo zīmi.
