因式分解x(a+b)+y(a+b)-搜答案-智慧作业帮

原式=（y-x）（a-b+c-b+a+c)=2*（y-x)(a-b+c)

x³(a+1)-xy(x-y)(a-b)+y³(b+1)=x³(a-b+b+1)-xy(x-y)(a-b)+y³(b+1)=x³(a-b)+x

4ab(a+b)^2-6a^2b(a+b)=2ab(a+b)[2(a+b)-3a]=2ab(a+b)(2b-a)(x+y)^2(x-y)+(x+y)(x-y)^2=(x+y)(x-y)[(x+y)+(

x^3(a+1)-xy(x-y)(a-b)+y^3(b+1)=ax^3+x^3-ayx^2+byx^2+axy^2-bxy^2+by^3+y^3=ax(x^2-xy+y^2)+by(x^2-xy+y^

2x²y-xy-3y=y(2x²－x－3)=y(x＋1)(2x－3)（-a+b）+c²（a-b）=c²（a-b）－(a－b)=(a－b)(c²－1)=

(1).将后面的（b-a）变成-（a-b）可以得到：(a-b)(x-y)+(a-b)(x+y)=(a-b)[(x-y)+(x+y)]=(a-b)(2x)=2x(a-b)(2).原式=3(y²

x(2a-b)+5y(2b-4a)=x(2a-b)-5y(4a-2b)=x(2a-b)-10y(2a-b)=(2a-b)(x-10y))

只要把相同的因子提取出来即可x^2y^2-4x=x*(xy^2-4)a(a-b)-2b(b-a)=a(a-b)+2b(a-b)=(a-b)*(a+2b)

3x(a-b)-2y(b-a)=3x(a-b)+2y(a-b)(括号内外同时变号）=（a-b)(3x+2y)(提取公因式（a-b))

(2x-3y)(a-b)+(3x-2y)(b-a)=(2x-3y-3x+2y)(a-b)=(-x-y)(a-b)=(x+y)(b-a)（a²+4b²）²-16a²

ab(x+y)(x-y)-xy(a+b)(a-b)=ab(x^2-y^2)-xy(a^2-b^2)=abx^2-aby^2-xya^2+xyb^2=ax(bx-ay)-by(ay-bx)=ax(bx-

(a-b)^2-6(b-a)+9.=（a-b-3）²25(x-y)^2+10(y-x)+1=[5(x-y)]^2-10(x-y)+1=[5(x-y)-1]²=(5x-5y-1)&#

（2x-3y)(a+b)+(3x-2y)(a+b)提取公因式（a+b）=(a+b)(2x-3y+3x-2y)=(a+b)(5x+5y)=5(a+b)(x+y)

(a-b)(x-y)-(b-a)(x+y)=(a-b)(x-y)+(a-b)(x+y)=(a-b)(x-y+x+y)=2(a-b)x

a（x-y）+b（y-x）+c（x-y）=(x-y)(a+b+c)有什么不明白可以对该题继续追问请及时选为满意答案,

(a-b)²(x-y)-(b-a)(y-x)²=(a-b)(x-y)（a-b+(x-y)）=(a-b)(x-y)×（a-b+x-y）再问：mn²(x-y)的三次方+m&#

（a-b)(x-y)-(b-a)(x-y)=(a-b)(x-y)+(a-b)(x-y)=2(a-b)(x-y)（a-b)(x-y)-(b-a)(x+y）=(a-b)(x-y)+(a-b)(x+y)=(

a²（y-x)+(x-y)=a²（y-x)-(y-x)=（y-x)(a²-1)=(y-x)(a+1)(a-1)再问：（3x-2）（2x-1）怎么写呢？再答：什么怎么写？（

原式=(a-b)(x²+xy-y²/4)
