X3-y3如何化简

X3-y3如何化简
X3-y3
=x³-x²y+x²y-y³
=x²(x-y)+y(x²-y²)
=x²(x-y)+y(x+y)(x-y)
=(x-y)(x²+xy+y²)

是分解因式吧
x^3-y^3
=(x-y)(x^2+xy+y^2)

（x-y）(x2+xy+y2)

x^3-y^3
=x^3-x^2*y+x^2*y-y^3
=x^2*(x-y)+y*(x^2-y^2)
=x^2*(x-y)+y*(x+y)*(x-y)
=(x-y)*(x^2+x*y+y^2)

x^3-y^3
原式=x^3-x^2*y+x^2*y-y^3
=x^2*(x-y)+y*(x^2-y^2)
=x^2*(x-y)+y*(x+y)*(x-y)
=(x-y)*(x^2+x*y+y^2)

X3-y3如何化简如何求x3,y3,能不能给个x3 y3的求解公式如图 x3-y3和x3+y3怎么因式分解 x3－y3;; 因式分解 x3+y3怎么因式分解? 因式分解 x3+8y3 分解因式 x3+y3! 化简求值:3(x2+xy)-2(x3-y3-3xy)+(-3xy-2y3),其中x=1,y=2 因式分解：x3-y3-x2y+xy2 x3+x2y-xy2-y3= 因式分解x3=8y3 因式分解：x2-y2+x3-y3 y2-y1/x2-x1-y4-y3/x4-x3//如何计算请尽量详细谢谢为什么(x3)2-(y3)2 =(x3+y3)(x3-y3)2 和 3 表示平方和立方写的详细些 matlab如何将一组数代入原方程的字母里?syms x1 x2 x3 x4 y1 y2 y3 y4 X1 X2 X3 X4 Y1 Y2 Y3 Y4A=[x1,y1,1,0,0,0,-x1*X1,-y1*X1;0,0,0,x1,y1,1,-x1*Y1,-y1*Y1;x2,y2,1,0,0,0,...-x2*X2,-y2*X2;0,0,0,x2,y2,1,-x2*Y2,-y2*Y2;x3,y3,1,0,0,0,-x3*X3,-y3*X3; x3+x-y-y3因式分解详细过程分解因式 x3+y3-x2y-xy2 分解因式x3+y3+z3-3xyz
