(a2-1)/(a2+2a+1)除以(a2-a)/(a+1) (a-2/(a+3)除以(a2-4)/(a2+6a+9)
化简:5a2-[a2+(5a2-2a)-2(a2-3a)].
(a2+5a+3)(a2+5a-2)-6因式分解
化简分式 化简分式 ( a2-9)/(a2+6a+9) +(a-3) /(a2+3a) - (a-a2) /(a-1)
已知a2-3a+1=0,那么4a2−9a−2+91+a2=( )
[1-(6+3a)/(a2+4a+4)]÷[(4a-4)/(a2+2a)]
(a2-4/a2-4a+3)×(a-3/a2+3a+2=?
2a-3b/b2-a2 -a+3b/a2-b2 +a+2b/a2-b2
(a-1)-(3a2-2a+1)
若a2-3a=-1,则3a3-9a2+4a+(3/a2+1)=?
化简 (2a2-1+2a)-3(a-1+a2)
若a2-2a=-2,求代数式3a2-6a+3的值.
