-x(6x+7)(x^2-36)=0

解

- x (6 x + 7) (x^{2} - 36) = 0

解

x = 0, x = - 6, x = 6, x = - \frac{7}{6}

+1

十進法表記

x = 0, x = - 6, x = 6, x = - 1.16666 \dots

解答ステップ

- x (6 x + 7) (x^{2} - 36) = 0

因数

- x (6 x + 7) (x^{2} - 36) : - x (x + 6) (x - 6) (6 x + 7)

- x (x + 6) (x - 6) (6 x + 7) = 0

零因子の原則を使用:

ab = 0

ならば

a = 0

または

b = 0

x = 0 or x + 6 = 0 or x - 6 = 0 or 6 x + 7 = 0

解く

x + 6 = 0 : x = - 6

解く

x - 6 = 0 : x = 6

解く

6 x + 7 = 0 : x = - \frac{7}{6}

解答は

x = 0, x = - 6, x = 6, x = - \frac{7}{6}
