x^4-18x^2=18x^2

解

x^{4} - 18 x^{2} = 18 x^{2}

解

x = 6, x = - 6, x = 0

解答ステップ

x^{4} - 18 x^{2} = 18 x^{2}

18 x^{2}

x^{4} - 36 x^{2} = 0

equationを

u = x^{2}

と以下で書き換える:

u^{2} = x^{4}

u^{2} - 36 u = 0

解く

u^{2} - 36 u = 0 : u = 36, u = 0

u = 36, u = 0

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = 36 : x = 6, x = - 6

解く

x^{2} = 0 : x = 0

解答は

x = 6, x = - 6, x = 0
