((x+3)(x-3))^2=100

解

((x + 3) (x - 3))^{2} = 100

解

x = 19, x = - 19, x = i, x = - i

解答ステップ

((x + 3) (x - 3))^{2} = 100

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

の場合, 解は

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

解く

(x + 3) (x - 3) = 100 : x = 19, x = - 19

解く

(x + 3) (x - 3) = - 100 : x = i, x = - i

解答は

x = 19, x = - 19, x = i, x = - i
