solvefor x,z^2= 324/972 (x^2+y^2)

解

解く

x, z^{2} = \frac{324}{972} (x^{2} + y^{2})

解

x = 3 z^{2} - y^{2}, x = - 3 z^{2} - y^{2}

解答ステップ

z^{2} = \frac{324}{972} (x^{2} + y^{2})

辺を交換する

\frac{324}{972} (x^{2} + y^{2}) = z^{2}

以下で両辺を乗じる:

3

x^{2} + y^{2} = 3 z^{2}

y^{2}

を右側に移動します

x^{2} = 3 z^{2} - y^{2}

x^{2} = f (a)

の場合, 解は

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

x = 3 z^{2} - y^{2}, x = - 3 z^{2} - y^{2}

solvefor x,x^2-3x-m(m+3)=0

so l v e f or x, x^{2} - 3 x - m (m + 3) = 0

solvefor x,3x^2y+2y=5x

so l v e f or x, 3 x^{2} y + 2 y = 5 x

(5(x^2+1))/(25)=10

\frac{5 ( x ^{2} + 1 )}{25} = 10

n(t)=0.1t^2-4t+90

n (t) = 0.1 t^{2} - 4 t + 90

solvefor a,f+f^2=-a^2

so l v e f or a, f + f^{2} = - a^{2}
