数学基本分式运算(2m-7)(2m-5)/(2m-3)怎么变变变=2m−9+8/(2m-3)数学基本分式运算(2m-7)(2m-5)/(2m-3)怎么变变变=2m−9+8/(2
数学基本分式运算(2m-7)(2m-5)/(2m-3) 怎么变变变=2m−9+ 8/(2m-3)
数学基本分式运算
(2m-7)(2m-5)/(2m-3) 怎么变变变=2m−9+ 8/(2m-3)
数学基本分式运算(2m-7)(2m-5)/(2m-3) 怎么变变变=2m−9+ 8/(2m-3)
(2m-7)(2m-5)/(2m-3) =(4m^2-24m+35)/(2m-3)=((2m-3)^2-6(2m-3)+8)/(2m-3)=2m−9+ 8/(2m-3)
(4m^2-24m+35)/(2m-3)=[(2m-9)*(2m-3)+8]/(2m-3)=2m-9+8/(2m-3)
