Resolver k^2+11k+30=y

$$k ^ { 2 } + 11 k + 30 = y$$

Resolver y

$$y=\left(k+5\right)\left(k+6\right)$$

Pasos da solución

Cambia de lado para que todos os termos variables estean no lado esquerdo.

$$y=k^{2}+11k+30$$

Resolver k (complex solution)

$$k=\frac{\sqrt{4y+1}-11}{2}$$

$$k=\frac{-\sqrt{4y+1}-11}{2}$$

Resolver k

$$k=\frac{\sqrt{4y+1}-11}{2}$$

$$k=\frac{-\sqrt{4y+1}-11}{2}\text{, }y\geq -\frac{1}{4}$$
