lcm+6m^2-4,m^2+,((3m-6))/((4m+15))m^2

解答

lcm

+ 6 m^{2} - 4, m^{2} +, \frac{( 3 m - 6 )}{( 4 m + 15 )} m^{2}

解答

\frac{6 m ^{4} ( 3 m + 2 ) ( 3 m - 2 ) ( m - 2 )}{4 m + 15}

求解步骤

找到

+ 6 m^{2} - 4, m^{2} +, \frac{( 3 m - 6 )}{( 4 m + 15 )} m^{2}

的最小公倍数

分解

6 m^{2} - 4 : 2 (3 m + 2) (3 m - 2)

分解

\frac{( 3 m - 6 )}{( 4 m + 15 )} m^{2} : \frac{3 m ^{2} ( m - 2 )}{4 m + 15}

将最高次数乘以每个因数:

2 \cdot 3 \cdot \frac{1}{4 m + 15} \cdot (3 m + 2) \cdot (3 m - 2) \cdot m^{2} \cdot (m - 2) \cdot (m^{2})

化简

\frac{6 m ^{4} ( 3 m + 2 ) ( 3 m - 2 ) ( m - 2 )}{4 m + 15}
