x²-4y²+x-2y=(x²-4y²)+(x-2y)=(x-2y)(x+2y)+(x-2y)=(x-2y)(x+2y+1)很高兴为您解答,祝你学习进步!【学习
原式=x²-6xy+9y²-14y²=(x-3y)²-14y²=(x-3y+√14y)(x-3y-√14y)
a(y-x)-2b(x-y)=a(y-x)+2b(y-x)=(y-x)(a+2b)
=(x-3y)²-3(x-3y)=(x-3y)(x-3y-3)
=[5(x＋y)]²－[4(x－y)]²=(5x＋5y＋4x－4y)(5x＋5y－4x＋4y)=(9x＋y)(x＋9y)
一：a(x-y)-x+y=a(x-y)-(x-y)=(a-1)(x-y)二：1.22²×3²-1.33²×4=（1.22×3）²-（1.33x2）²=
(x+y)²-6x²+6y²+9(x-y)²=x²+2xy+y²-6x²+6y²+9x²-18xy+9y
原式=x²-Y²-x-5y-6=(x²-x+1/4)-(Y²+5y+25/4)=(x-1/2)²-（Y+5/2)²=[(x-1/2)+(Y+
x^2-x-4y^2+2y=(x^2-4y^2)-(x-2y)=(x+2y)(x-2y)-(x-2y)=(x-2y)(x+2y-1)
(x-2)(x-3)
原式=x(x²y+3)-2y(x²y+3)=(x²y+3)(x-2y)
12x^2+xy-6y^2=(4x+3y)(3x-2y)
（X-3）（X-2）
你的式子是无法分解的,已经是最简代数式了x^2-xy+y^2=（x-y/2）^2+3y^2/4恒大于0,无法分解
原式=(x+y)(x-y)[(x+y)(x-y)-(x²+y²)]=(x+y)(x-y)(x²-y²-x²-y²)=-2y²(x+
[(x-y)x]6+[(y-x)y]6=(x-y)6x6+(y-x)6y6=(x-y)6(x6+y6)=(x-y)6[(x2)3+(y2)3]=(x-y)6(x2+y2)(x4-x2y2+y4)欢迎来
3x²-6xy-3y=3(x²-2xy-y)你的题目是不是错了啊,估计是3x²-6xy+3y²3x²-6xy+3y²=3(x²-2
错了是3x³+6x²y=3x²(x+2y)再问：���再答：ֱ����ȡ����ʽ���ɰ�再问：����һ��3x������+6x��ƽ��y��֮x������-4
x平方+5x-6=(x-6)(x+1)
6x³y（x-y)³-4xy³(y-x)²＝6x³y（x-y)³-4xy³(x-y)²=2xy(x-y)²[3
