Réitigh h^2+10h-2w=0

$$h ^ { 2 } + 10 h - 2 w = 0$$

Réitigh do w.

$$w=\frac{h\left(h+10\right)}{2}$$

Céimeanna chun Cothromóidí Líneacha a Réiteach

Bain h^{2} ón dá thaobh. Is ionann rud ar bith a dhealaítear ó nialas agus a shéanadh.

$$10h-2w=-h^{2}$$

Bain 10h ón dá thaobh.

$$-2w=-h^{2}-10h$$

Roinn an dá thaobh faoi -2.

$$\frac{-2w}{-2}=-\frac{h\left(h+10\right)}{-2}$$

Má roinntear é faoi -2 cuirtear an iolrúchán faoi -2 ar ceal.

$$w=-\frac{h\left(h+10\right)}{-2}$$

Roinn -h\left(10+h\right) faoi -2.

$$w=\frac{h\left(h+10\right)}{2}$$

Réitigh do h. (complex solution)

$$h=\sqrt{2w+25}-5$$

$$h=-\sqrt{2w+25}-5$$

Réitigh do h.

$$h=\sqrt{2w+25}-5$$

$$h=-\sqrt{2w+25}-5\text{, }w\geq -\frac{25}{2}$$
