化简 ((8m^2-2))/((2m^2))

解答

化简

\frac{( 8 m ^{2} - 2 )}{( 2 m ^{2} )}

\frac{( 2 m + 1 ) ( 2 m - 1 )}{m ^{2}}

求解步骤

\frac{8 m ^{2} - 2}{2 m ^{2}}

因式分解

8 m^{2} - 2 : 2 (4 m^{2} - 1)

= \frac{2 ( 4 m ^{2} - 1 )}{2 m ^{2}}

因式分解

4 m^{2} - 1 : (2 m + 1) (2 m - 1)

= \frac{2 ( 2 m + 1 ) ( 2 m - 1 )}{2 m ^{2}}

约分:

2

= \frac{( 2 m + 1 ) ( 2 m - 1 )}{m ^{2}}
