3x^5-24x^2=0

解答

3 x^{5} - 24 x^{2} = 0

解答

x = 0, x = 2, x = - 1 + 3 i, x = - 1 - 3 i

求解步骤

3 x^{5} - 24 x^{2} = 0

因式分解

3 x^{5} - 24 x^{2} : 3 x^{2} (x^{3} - 8)

3 x^{2} (x^{3} - 8) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

x = 0 or x^{3} - 8 = 0

解

x^{3} - 8 = 0 : x = 2, x = - 1 + 3 i, x = - 1 - 3 i

解为

x = 0, x = 2, x = - 1 + 3 i, x = - 1 - 3 i
