-9=t^8-12

解

- 9 = t^{8} - 12

解

t = 43, t = - 43, t = 43 i, t = - 43 i, t = \frac{4 3}{2} + \frac{8 3}{2} i, t = - \frac{4 3}{2} - \frac{8 3}{2} i, t = \frac{4 3}{2} - \frac{8 3}{2} i, t = - \frac{4 3}{2} + \frac{8 3}{2} i

解答ステップ

- 9 = t^{8} - 12

辺を交換する

t^{8} - 12 = - 9

t^{8} = 3

equationを

u = t^{2}

と以下で書き換える:

u^{4} = t^{8}

u^{4} = 3

解く

u^{4} = 3 : u = 3, u = - 3, u = 3 i, u = - 3 i

u = 3, u = - 3, u = 3 i, u = - 3 i

再び

u = t^{2}

に置き換えて以下を解く:

t

解く

t^{2} = 3 : t = 43, t = - 43

解く

t^{2} = - 3 : t = 43 i, t = - 43 i

解く

t^{2} = 3 i : t = \frac{4 3}{2} + \frac{8 3}{2} i, t = - \frac{4 3}{2} - \frac{8 3}{2} i

解く

t^{2} = - 3 i : t = \frac{4 3}{2} - \frac{8 3}{2} i, t = - \frac{4 3}{2} + \frac{8 3}{2} i

解答は

t = 43, t = - 43, t = 43 i, t = - 43 i, t = \frac{4 3}{2} + \frac{8 3}{2} i, t = - \frac{4 3}{2} - \frac{8 3}{2} i, t = \frac{4 3}{2} - \frac{8 3}{2} i, t = - \frac{4 3}{2} + \frac{8 3}{2} i

x^3-x^2-11x+3=0

x^{3} - x^{2} - 11 x + 3 = 0

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

(x - 2)^{3} = 4

0 = x^{4} - 36

(x^2-8)(x^2-1)=8

(x^{2} - 8) (x^{2} - 1) = 8
