(2x^3y^3-2x^3y+1/8^4+y)/(-1/2x^3y)怎么算!
(2x^3y^3-2x^3y+1/8^4+y)/(-1/2x^3y)
怎么算!
(2x^3y^3-2x^3y+1/8^4+y)/(-1/2x^3y)怎么算!
(2x^3y^3-2x^3y+1/8^4+y)/(-1/2x^3y)
=-2(2x^3y^3-2x^3y+1/8^4+y)/(x^3y)
=-2(2y^2-2)+2(1/8^4+y)/(x^3y)
=-4y^2-4+2/8^4(x^3y)+2y/(x^3y)
=-4y^2-4+2/2^12(x^3y)+2/x^3
=-4y^2-4+1/2^11x^3y+2/x^3
计算:1/(x-y)-1/(x+y)-2y/(x^2+y^2)-4y^3/(x^4+y^4)-8x^7/(x^8+y^8)
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
9y=3x-(x-1),4(x+y)-(2x+4)=8y
4x-3y/x-2y÷6y-8x/y-2x
81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
计算(x^8-x^7y+x^5y^3-x^4y^4+x^3y^5-x^y^7+y^8)(x^2+xy+y^2)
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)
x+y+2(-x-y+1)=3(1-y-x)-4-(y+x-1),x+y=?
{x+y=1 ,xy=-6{x(2x-3)=0,y=x²-1{(3x+4y-3)(3x+4y+3)=0,3x+2y=5{(x-y+2)(x+y)=0,x²+y²=8{(x+y)((x+y-1)=0,(x-y)(x-y-1)=0
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
x^3+2x^2y-4x-8y
(x+3y-4)(2x-y)
计算(2x-3y)(x+4y)-(3x+y)(x-2y)(2x-3y)(x+4y)-(3x+y)(x-2y)
因式分解(x-2y)(x-3y)+(x-4y)(x-5y)+(x-3y)(x-5y)+(x-2y)(x-4y)
先化简 再求值 (2x-y)(y+x)-(x-2y)(2y+x)-(-3y+x)^2其(√x+1)+y^2+4=-4y
化简[(3x+4y)^2-(2x+y)(2x-y)+(-x+y)(5x-y)]除以-2y,其中x=-1,y=1
已知x-y=1,求[(x+2y)^2+(2x+y)(x-4y)-3(x+y)(x-y)]除以y的值大神们帮帮忙
