(x^2-7)^2=25

解

(x^{2} - 7)^{2} = 25

解

x = 23, x = - 23, x = 2, x = - 2

+1

十進法表記

x = 3.46410 \dots, x = - 3.46410 \dots, x = 1.41421 \dots, x = - 1.41421 \dots

解答ステップ

(x^{2} - 7)^{2} = 25

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

の場合, 解は

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

解く

x^{2} - 7 = 25 : x = 23, x = - 23

解く

x^{2} - 7 = - 25 : x = 2, x = - 2

解答は

x = 23, x = - 23, x = 2, x = - 2
