( x + y )" - 4y"
= ( x + y )" - ( 2y )"
= ( x + y - 2y )( x + y + 2y )
= ( x - y )( x + 3y )
( x + y )" - ( x - y + 1 )"
= [ ( x + y ) + ( x - y + 1 ) ][ ( x + y ) - ( x - y + 1 ) ]
= ( x + y + x - y + 1 )( x + y - x + y - 1 )
= ( 2x + 1 )( 2y - 1 )
{(x²+y²)-(x-y)+2y(x-y)}/4y
y'=(y/x)^2+y/x+4微分方程

(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
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-2y)(x+y)+(x+y)计算
计算:(x-y)^2-(x+y)(x-y)
2(x-y)²-3(x-y)(-y-x)
化简x+y分之x²-y²-2X-y分之4x(x-y)+y²
[(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)
