p^3-144p=0

解答

p^{3} - 144 p = 0

解答

p = 0, p = - 12, p = 12

求解步骤

p^{3} - 144 p = 0

因式分解

p^{3} - 144 p : p (p + 12) (p - 12)

p (p + 12) (p - 12) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

p = 0 or p + 12 = 0 or p - 12 = 0

解

p + 12 = 0 : p = - 12

解

p - 12 = 0 : p = 12

解为

p = 0, p = - 12, p = 12
