Datrys TC=0.5Q^2+10Q+50

$$T C = 0.5 Q ^ { 2 } + 10 Q + 50$$

Datrys ar gyfer C

$$\left\{\begin{matrix}C=\frac{\left(Q+10\right)^{2}}{2T}\text{, }&T\neq 0\\C\in \mathrm{R}\text{, }&Q=-10\text{ and }T=0\end{matrix}\right.$$

Camau ar gyfer Datrys Hafaliad Llinol

Mae'r hafaliad yn y ffurf safonol.

$$TC=\frac{Q^{2}}{2}+10Q+50$$

Rhannu’r ddwy ochr â T.

$$\frac{TC}{T}=\frac{2\left(\frac{Q}{2}+5\right)^{2}}{T}$$

Mae rhannu â T yn dad-wneud lluosi â T.

$$C=\frac{2\left(\frac{Q}{2}+5\right)^{2}}{T}$$

Rhannwch 2\left(5+\frac{Q}{2}\right)^{2} â T.

$$C=\frac{\left(Q+10\right)^{2}}{2T}$$

Datrys ar gyfer Q

$$Q=\sqrt{2CT}-10$$

$$Q=-\sqrt{2CT}-10\text{, }\left(T\geq 0\text{ and }C\geq 0\right)\text{ or }\left(C\leq 0\text{ and }T\leq 0\right)$$
