\frac{5\left(x+h\right)+7-\left(-5x^{2}+10x+7\right)}{h}
Ikkombina -5\left(x+h\right) u 10\left(x+h\right) biex tikseb 5\left(x+h\right).
\frac{5x+5h+7-\left(-5x^{2}+10x+7\right)}{h}
Uża l-propjetà distributtiva biex timmultiplika 5 b'x+h.
\frac{5x+5h+7+5x^{2}-10x-7}{h}
Biex issib l-oppost ta' -5x^{2}+10x+7, sib l-oppost ta' kull terminu.
\frac{-5x+5h+7+5x^{2}-7}{h}
Ikkombina 5x u -10x biex tikseb -5x.
\frac{-5x+5h+5x^{2}}{h}
Naqqas 7 minn 7 biex tikseb 0.
