(4x+y)(y-4x)-x(5y-16x)因式分解(4x+y)(y-4x)-x(5y-16x)因式分解(4x+y)(y-4x)-x(5y-16x)因式分解原式=y^2-16x^2-5xy+16x^2
(4x+y)(y-4x)-x(5y-16x) 因式分解
(4x+y)(y-4x)-x(5y-16x) 因式分解
(4x+y)(y-4x)-x(5y-16x) 因式分解
原式=y^2-16x^2-5xy+16x^2
=y^2-5xy
=y(y-5x)
(4x+y)(y-4x)-x(5y-16x) 因式分解
(x-y)^3×(y-x)^4+(x-y)^2×(y-x)^5
(x+y)^6/(x+y)^4-(x-y)^5/(x-y)^3 化简 ..
[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)请帮我一下写两道计算题[(x+y)(x-y)-(x-y)的平方+2y(x-y)]除以(4y)[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除以(4x)
(4x-3y)-[(-13y-x)+(x-y)]-5x
{(x²+y²)-(x-y)+2y(x-y)}/4y
把(x+y)、(x-y)看作整体,进行合并同类项;3(x-y)-4(x+y)+5(x-y)-(x+y).
.先化简再求值:(2x+y)(2x+y)-(2x-y)平方其中X,Y满足X平方+Y平方-2X+4Y+5=0
(y-x)^4(x-y)^3+2(x-y)^6(y-x)
y'=(y/x)^2+y/x+4微分方程
12(x+y)^3(y-x)/【4(x+y)^2(x-y)】
(x-y+4xy/x-y)(x+y-4xy/x-y)
(x-2y)²+(2x-4y)(x+y)+(x+y)²
计算:[(x+y)³-2(x+y)²-4(x+y)]÷(x+y)
2分之x+y+3分之x-y;4(x+y)-(x-y)谢谢了,
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
{5(x-3y)-6=2x+1 3(x+6y)+4=9y+19 {3分之2(x-y)=4分之x+y-1 6)x+y)=4(2x-y)+16
(x-4y)分之(3x)+(4y-x)分之(x+y)-(x-4y)分之(7y)
