你会么?
追答我觉得你的式子有问题,我想看一下原题。
因式分解 (x-y)²-16(x+y)²
(x-y)²-16(x+y)²=(x-y+4x+4y)(x-y-4x-4y)=-(5x+3y)(5x+5y)愿我的回答对你有帮助!如有疑问请追问,愿意解疑答惑。如果明白,并且解决了你的问题,请及时采纳为最佳答案!O(∩_∩)O
(x-y)²+y(y-x)因式分解?
因式分解 (x-y)²+y(y-x)=(x-y)²-y(x-y)=(x-y-y)(x-y)=(x-2y)(x-y)
把(x+y)的平方-(x-y)的平方因式分解
(x+y)²-(x-y)²=[(x+y)+(x-y)][(x+y)-(x-y)]=(x+y+x-y)(x+y-x+y)=2x*2y =4xy 希望采纳
(x+y)^3-(x-y)^2(x+y)因式分解
原式为:(x+y)³-(x-y)²(x+y)=(x+y)(x+y)²-(x+y)(x-y)²=(x+y)【(x+y)²-(x-y)²】=(x+y)2x2y =4xy(x+y)
将(x+y)²-(x-y)²因式分解,其结果为? 求详细过程
(x+y)²-(x-y)²=((x+y)+(x-y))*((x+y)-(x-y))=(2x)*(2y)
谁帮帮忙,因式分解
1、x²(x-y)+y²(y-x)=x²(x-y)y²(x-y)=(x²-y²)(x-y)=(x+y)(x-y)(x-y)=(x+y)(x-y)²2、a^4-9a^2b^2 =a^2(a^2-9b^2)=a^2(a+3b)(a-3b)3、a^2-a-b^2-b =(a^2-b^2)-(a+b)=(a+b...
x²+y²-xy-x-y因式分解?
x² + y² - xy - x - y = (x² - 2xy + y²) - (x + y)= (x - y)² - (x + y)接下来,我们可以使用差的平方公式将第一项进行因式分解:(x - y)² - (x + y) = (x - y)² - (x + y)² + 2(x + y)= (x ...
...平方减y乘括号y-x括起来的平方等于多少,因式分解?
这道算式题:首先展开平方差的公式,然后去括号,整理多项式提取公因式,在展开立方差的公式,提取公因式整理之后,最终的结果是有关x与y的差的立方。
x²(x-y)+y²(y-x)
因式分解吗?如果是:原式=x²(x-y) + y²[-(x-y)]=x²(x-y) - y²(x-y)=(x-y)(x²-y²)=(x-y)(x+y)(x-y)=(x+y)(x-y)²
因式分解-xy²(x+y)³+x(x+y)²
原式=x(x+y)²[1-y²(x+y)]
