9(a-b)²+12(a²-b²)+4(a+b)²
a³-10a²+25a
x²+2x+1-y²
25（m+n-3）²-9（3m-2n）²
a³-10a²+25a
x²+2x+1-y²
25（m+n-3）²-9（3m-2n）²
9(a-b)²+12(a²-b²)+4(a+b)²
=(3(a-b))+2*3*2(a+b)(a-b)+(2(a+b))²
=(3(a-b)+2(a+b))²
=(5a-b)²
a³-10a²+25a
=a(a²-2*5*a+5²)
=a(a-5)²
x²+2x+1-y²
=(x+1)²-y²
=(x+1+y)(x+1-y)
25（m+n-3）²-9（3m-2n）²
=(5(m+n-3))²-(3(3m-2n))²
=(5(m+n-3)+3(3m-2n))(5(m+n-3)-3(3m-2n))
=(14m-n-15)(-4m+11n-15)
=(3(a-b))+2*3*2(a+b)(a-b)+(2(a+b))²
=(3(a-b)+2(a+b))²
=(5a-b)²
a³-10a²+25a
=a(a²-2*5*a+5²)
=a(a-5)²
x²+2x+1-y²
=(x+1)²-y²
=(x+1+y)(x+1-y)
25（m+n-3）²-9（3m-2n）²
=(5(m+n-3))²-(3(3m-2n))²
=(5(m+n-3)+3(3m-2n))(5(m+n-3)-3(3m-2n))
=(14m-n-15)(-4m+11n-15)
(a-b)(a+b)²-(a+b)(a-b)²+2b(a²+b²)
(a-b)²-12(a+b)+36
(a+b)²-12(a+b)+36
4a（a-b）+b²
因式分解a(a-b)+(b-a)²
a(a-b)+(a-b)²因式分解
因式分解9(a-b)²+12(a²-b²)+4(a+b)²
9(a-b)²+12(a²-b²)+4(a+b)²因式分解的结果
【(a+b)³-2(a+b)²-4(a+b)】÷(a+b)=?
已知a.b满足b-a=-2014,求代数式【（a+b）（a-b）-（a-b)²-2b（b-a)】/（4b）的值
因式分解a²(a-b)-b²(a-b)
计算：(a-b)²(a-b)³(b-a)
