-4x^2y^2+25/9a^2b^2-4x^2y^2+25/9a^2b^2-4x^2y^2+25/9a^2b^2原式=(5/3ab)²-(2xy)²=(5/3ab+2xy)(5/
-4x^2y^2+25/9a^2b^2
-4x^2y^2+25/9a^2b^2
-4x^2y^2+25/9a^2b^2
原式=(5/3ab)²-(2xy)²
=(5/3ab+2xy)(5/3ab-2xy)
通分 a/(y-x)^2,b/(x-y)(x+y)
因式分解a(x-y)+b(y-x)+(2x-y)
4(a+b)^2(x-y)+9(a-b)^2(y-x)怎么算
(2x+y)(2x-3y)+x(2y+y) 2a(x-y)-4b(x-y)
分解因式(1) 25X^2-16Y^2 (2) (A-B)(X-Y)-(B-A)(X+Y) (3)A^2-4AB+4B^2 (4)4+12(X-Y)+9(X-Y)^2
分解因式,25x^2-16y^3;(a-b)(x-y)(b-a)(x+y);a^2-4ab+4b^2;4+12(x-y)+9(x-y)^2
因式分解:4a(x-y)-2b(x-y)
4a(x-y)-2b(y-x)
4a(x-y)-2b(y-x)
(x+y)(a-2b)
因式分解:a(x-y)^2+b(y-x)^3 4(x-y)^2+8(y-x)(x+y)1.a(x-y)^2+b(y-x)^3 2.4(x-y)^2+8(y-x)(x+y)
(2a-b)(4a²+b²)(b+a) (2x-y)²-4(x-y)(x+2y)
(x+y)²+2(y-x) 因式分解 怎么弄 我这还有几道题(x+y)²-(x+y)(x-z)+(x+y)(y+z)X(X-a)(x-b)-y(a-x)(b-x)x(x+y)(x-y)-x(x+y)²(2a+b)(2a-3b)-3b(2a+b)(a+b)²-9(a-b)²(a²+b²)²-a²b²9(x-y)-y&
因式分解-5a^2+25a;25x^2-16y^2;x^3-25x;x^2(x-y)+y^2(y-x);x^2y^4-16x^2;(a+b)^2+2(a+b)+1
(2a+b)(2a-3b)+3a(2a+b)和x(x+y)(x-y)-x(x+y)²4a(x+y)-6x-6y和啊a(a-b)-ab+b²
因式分解,xy-y (a-b)x-(a-b)x² x²-1因式分解,xy-y (a-b)x-(a-b)x² x²-1 2a²-2b² 9x²-4分之1y²
12ab^2(y-x)+9b^3(x-y)+4a^2b(x-y)因式分解
1(x-3x-1)(x+3y-1)2(3x-2y+1/4)²3(a+b)²-(a-b)²4 [2x²-(x+y)(x-y)][(-x-y)×(y-x)+2y²],其中x=1 y=25[(0.5x-y)²+(0.5x+y)²](0.5x²-2y²)6(a+3b)²-2(a+3b)(a-3b)+(a-3b)²7
