solvefor k,k^2=n^2+3n+15

解

解く

k, k^{2} = n^{2} + 3 n + 15

解

k = n^{2} + 3 n + 15, k = - n^{2} + 3 n + 15

解答ステップ

k^{2} = n^{2} + 3 n + 15

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

k = n^{2} + 3 n + 15, k = - n^{2} + 3 n + 15

(x-4)^3=x(x^2+2x)

(x - 4)^{3} = x (x^{2} + 2 x)

solvefor x, r/f (x)=2x^2-2x-12

so l v e f or x, \frac{r}{f} (x) = 2 x^{2} - 2 x - 12

a(x^2+1)=x(a^2+1)

a (x^{2} + 1) = x (a^{2} + 1)

solvefor x,f(x^2+y^2+z^2z^2-2xy)=0

so l v e f or x, f (x^{2} + y^{2} + z^{2} z^{2} - 2 x y) = 0
