((D+3I)^2+4I)^2y=0

解

((D + 3 I)^{2} + 4 I)^{2} y = 0

I = \frac{- 3 D - 2 + 2 3 D + 1}{9}, I = - \frac{3 D + 2 3 D + 1 + 2}{9}, y = 0

解答ステップ

((D + 3 I)^{2} + 4 I)^{2} y = 0

零因子の原則を使用:

ab = 0

ならば

a = 0

または

b = 0

(D + 3 I)^{2} + 4 I = 0 or y = 0

解く

(D + 3 I)^{2} + 4 I = 0 : I = \frac{- 3 D - 2 + 2 3 D + 1}{9}, I = - \frac{3 D + 2 3 D + 1 + 2}{9}

y = 0

解答は

I = \frac{- 3 D - 2 + 2 3 D + 1}{9}, I = - \frac{3 D + 2 3 D + 1 + 2}{9}, y = 0
