d^2j^5x^4-22x^2+8=2

解

d^{2} j^{5} x^{4} - 22 x^{2} + 8 = 2

解

x = \frac{11 + - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = - \frac{11 + - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = \frac{11 - - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = - \frac{11 - - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}

d^{2} j^{5} x^{4} - 22 x^{2} + 6 = 0

equationを

u = x^{2}

と以下で書き換える:

u^{2} = x^{4}

d^{2} j^{5} u^{2} - 22 u + 6 = 0

解く

d^{2} j^{5} u^{2} - 22 u + 6 = 0 : u = \frac{11 + - 6 d ^{2} j ^{5} + 121}{d ^{2} j ^{5}}, u = \frac{11 - - 6 d ^{2} j ^{5} + 121}{d ^{2} j ^{5}}; j \neq = 0

u = \frac{11 + - 6 d ^{2} j ^{5} + 121}{d ^{2} j ^{5}}, u = \frac{11 - - 6 d ^{2} j ^{5} + 121}{d ^{2} j ^{5}}; j \neq = 0

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = \frac{11 + - 6 d ^{2} j ^{5} + 121}{d ^{2} j ^{5}} : x = \frac{11 + - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = - \frac{11 + - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}

解く

x^{2} = \frac{11 - - 6 d ^{2} j ^{5} + 121}{d ^{2} j ^{5}} : x = \frac{11 - - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = - \frac{11 - - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}

解答は

x = \frac{11 + - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = - \frac{11 + - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = \frac{11 - - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}, x = - \frac{11 - - 6 d ^{2} j ^{5} + 121}{d j ^{2} j}
