solvefor x,x^2-4y^2+9z^2=36

解

解く

x, x^{2} - 4 y^{2} + 9 z^{2} = 36

x = 36 + 4 y^{2} - 9 z^{2}, x = - 36 + 4 y^{2} - 9 z^{2}

解答ステップ

x^{2} - 4 y^{2} + 9 z^{2} = 36

4 y^{2}

を右側に移動します

x^{2} + 9 z^{2} = 36 + 4 y^{2}

9 z^{2}

を右側に移動します

x^{2} = 36 + 4 y^{2} - 9 z^{2}

x^{2} = f (a)

の場合, 解は

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

x = 36 + 4 y^{2} - 9 z^{2}, x = - 36 + 4 y^{2} - 9 z^{2}
