solvefor x,2(x^4-y^4)=350

解

解く

x, 2 (x^{4} - y^{4}) = 350

解

x = 175 + y^{4}, x = - 175 + y^{4}, x = i 4 175 + y^{4}, x = - i 4 175 + y^{4}

解答ステップ

2 (x^{4} - y^{4}) = 350

以下で両辺を割る

2

x^{4} - y^{4} = 175

y^{4}

を右側に移動します

x^{4} = 175 + y^{4}

equationを

u = x^{2}

と以下で書き換える:

u^{2} = x^{4}

u^{2} = 175 + y^{4}

解く

u^{2} = 175 + y^{4} : u = 175 + y^{4}, u = - 175 + y^{4}

u = 175 + y^{4}, u = - 175 + y^{4}

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = 175 + y^{4} : x = 175 + y^{4}, x = - 175 + y^{4}

解く

x^{2} = - 175 + y^{4} : x = i 4 175 + y^{4}, x = - i 4 175 + y^{4}

解答は

x = 175 + y^{4}, x = - 175 + y^{4}, x = i 4 175 + y^{4}, x = - i 4 175 + y^{4}

(x-1)(x+2)-x^2(x+2)=21

(x - 1) (x + 2) - x^{2} (x + 2) = 21

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

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

3x^4-24x^3+48x^2+x-4=0

3 x^{4} - 24 x^{3} + 48 x^{2} + x - 4 = 0

solvefor x,x^4+y^4=0

so l v e f or x, x^{4} + y^{4} = 0

x^3-5x^2+8x-4=0

x^{3} - 5 x^{2} + 8 x - 4 = 0
