solvefor x,x^4-10x^2+29=8

解

解く

x, x^{4} - 10 x^{2} + 29 = 8

解

x = 7, x = - 7, x = 3, x = - 3

+1

十進法表記

x = 2.64575 \dots, x = - 2.64575 \dots, x = 1.73205 \dots, x = - 1.73205 \dots

解答ステップ

x^{4} - 10 x^{2} + 29 = 8

8

x^{4} - 10 x^{2} + 21 = 0

equationを

u = x^{2}

と以下で書き換える:

u^{2} = x^{4}

u^{2} - 10 u + 21 = 0

解く

u^{2} - 10 u + 21 = 0 : u = 7, u = 3

u = 7, u = 3

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = 7 : x = 7, x = - 7

解く

x^{2} = 3 : x = 3, x = - 3

解答は

x = 7, x = - 7, x = 3, x = - 3

(x^2-4)^2=(x+4)^2+32

(x^{2} - 4)^{2} = (x + 4)^{2} + 32

2 x^{3} + 7 x^{2} = 15 x

8x^3-4x^2-4x+1=0

8 x^{3} - 4 x^{2} - 4 x + 1 = 0

solvefor x,z=(3x+2y)^5

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

x^3-8x^2+9x+18=0

x^{3} - 8 x^{2} + 9 x + 18 = 0
