\frac{16 a ^{2} + 12 ab + 9 b ^{3}}{2 ( 16 a ^{2} + 12 ab + 9 b ^{2} )}

\frac{16 a ^{2} + 12 ab + 9 b ^{3}}{32 a ^{2} + 24 ab + 18 b ^{2}}

求解步骤

\frac{16 a ^{2} + 12 ab + 9 b ^{3}}{2 ( 16 a ^{2} + 12 ab + 9 b ^{2} )}

乘开

2 (16 a^{2} + 12 ab + 9 b^{2}) : 32 a^{2} + 24 ab + 18 b^{2}

= \frac{16 a ^{2} + 12 ab + 9 b ^{3}}{32 a ^{2} + 24 ab + 18 b ^{2}}
