Leysa n^2-11n+24=y

$$n ^ { 2 } - 11 n + 24 = y$$

Leystu fyrir y

$$y=\left(n-8\right)\left(n-3\right)$$

Lausnarskref

Skipta um hliðar svo allir liðir breytunnar séu vinstra megin.

$$y=n^{2}-11n+24$$

Leystu fyrir n (complex solution)

$$n=\frac{\sqrt{4y+25}+11}{2}$$

$$n=\frac{-\sqrt{4y+25}+11}{2}$$

Leystu fyrir n

$$n=\frac{\sqrt{4y+25}+11}{2}$$

$$n=\frac{-\sqrt{4y+25}+11}{2}\text{, }y\geq -\frac{25}{4}$$
