分解因式181^2-61^2/301^2-181^2求求高手了(181^2-61^2)/(301^2-181^2)分解因式181^2-61^2/301^2-181^2求求高手了(181^2-61^2)
分解因式181^2-61^2/301^2-181^2求求高手了(181^2-61^2)/(301^2-181^2)
分解因式181^2-61^2/301^2-181^2求求高手了
(181^2-61^2)/(301^2-181^2)
分解因式181^2-61^2/301^2-181^2求求高手了(181^2-61^2)/(301^2-181^2)
(181^2-61^2)/(301^2-181^2)
=(181+61)(181-61)/(301+181)(301-181)
=242*120/482*120
=242/482
=121/241
[(181+61)(181-61)]/[(301+181)(301-181)]
=(342*120)/(482*120)
=342/482
