solvefor c,c^1c^2=r^1+r^2

解

解く

c, c^{1} c^{2} = r^{1} + r^{2}

解

c = 3 r + r^{2}, c = - \frac{3 r + r ^{2}}{2} + \frac{3 r + r ^{2} 3}{2} i, c = - \frac{3 r + r ^{2}}{2} - \frac{3 r + r ^{2} 3}{2} i

解答ステップ

c^{1} c^{2} = r^{1} + r^{2}

簡素化

c^{3} = r + r^{2}

x^{3} = f (a)

では, 解は

x = 3 f (a), 3 f (a) \frac{- 1 - 3 i}{2}, 3 f (a) \frac{- 1 + 3 i}{2}

c = 3 r + r^{2}, c = 3 r + r^{2} \frac{- 1 + 3 i}{2}, c = 3 r + r^{2} \frac{- 1 - 3 i}{2}

簡素化

3 r + r^{2} \frac{- 1 + 3 i}{2} : - \frac{3 r + r ^{2}}{2} + \frac{3 r + r ^{2} 3}{2} i

簡素化

3 r + r^{2} \frac{- 1 - 3 i}{2} : - \frac{3 r + r ^{2}}{2} - \frac{3 r + r ^{2} 3}{2} i

c = 3 r + r^{2}, c = - \frac{3 r + r ^{2}}{2} + \frac{3 r + r ^{2} 3}{2} i, c = - \frac{3 r + r ^{2}}{2} - \frac{3 r + r ^{2} 3}{2} i
