(x^2+16x)^2=17^2

解

(x^{2} + 16 x)^{2} = 1 7^{2}

解

x = 1, x = - 17, x = - 8 + 47, x = - 8 - 47

+1

十進法表記

x = 1, x = - 17, x = - 1.14434 \dots, x = - 14.85565 \dots

解答ステップ

(x^{2} + 16 x)^{2} = 1 7^{2}

1 7^{2} = 289

(x^{2} + 16 x)^{2} = 289

(g (x))^{2} = f (a)

の場合, 解は

g (x) = f (a), - f (a)

解く

x^{2} + 16 x = 289 : x = 1, x = - 17

解く

x^{2} + 16 x = - 289 : x = - 8 + 47, x = - 8 - 47

解答は

x = 1, x = - 17, x = - 8 + 47, x = - 8 - 47
