(a2-2ab+2b2)-(2a2-2ab-3ab2)化简(a2-2ab+2b2)-(2a2-2ab-3ab2)化简(a2-2ab+2b2)-(2a2-2ab-3ab2)化简(a²-2ab+
(a2-2ab+2b2)-(2a2-2ab-3ab2)化简
(a2-2ab+2b2)-(2a2-2ab-3ab2)
化简
(a2-2ab+2b2)-(2a2-2ab-3ab2)化简
(a²-2ab+2b²)-(2a²-2ab-3ab²)
=a²-2ab+2b²-2a²+2ab+3ab²
=-a²+2b²+3ab²
a2-2ab+b2
已知a2+AB=3,AB-B2= -2求a2+b2,a+2ab-b2
(a2+2ab+b2)-(a2-2ab+b2)化简
(3a2-3ab+2b2)+(a2+4ab-2b2)=4a2+ab+b2
(a2-b2)/(a2+2ab+b2)*(a3+b3)
化简:(a2-b2)/(a2+2ab+b2)÷(2a-2b)/(a+b)
2a-3b/b2-a2 -a+3b/a2-b2 +a+2b/a2-b2
2a-3b/b2-a2 -a+3b/a2-b2 +a+2b/a2-b2
已知a(a-1)-(a2-b)=2,求(a2+b2)/2-ab a2,b2为a方b方
化简 3a2-ab/3a2+5ab-2b2
如果b分之a=2,求a2+b2分之a2-ab+b2
若a2+b2-6a+2b+10=0 ,求a2+b2-ab
如果a/b=2,则a2-ab+b2/a2+b2=?
a/b=2,则a2-ab+b2/a2+b2=?
a2b+ab2分之a2+2ab+b2-(a2-ab2分之a2-2ab+b2)
a/b=2,则a2-ab+b2/a2+b2=?a2的意思是a的平方
计算:a2-2ab/-ab+b2÷(a2/a-b÷2ab/2b-a)
化简2a2-b2+ab-2ab-2a+b
