化简 (sqrt(216)-x)(sqrt(216)-x)(x)

解答

化简

(216 - x) (216 - x) (x)

x (216 - 126 x + x^{2})

求解步骤

(216 - x) (216 - x) (x)

使用法则:

(a) = a

(x) = x

= (216 - x) (216 - x) x

使用指数法则:

aa = a^{2}

(216 - x) (216 - x) = (216 - x)^{2}

= (216 - x)^{2} x

= x (216 - x)^{2}

展开

(216 - x)^{2} : 216 - 126 x + x^{2}

= x (216 - 126 x + x^{2})
