(2x-y)^2-8(2x+y)-20因式分解(2x-y)^2-8(2x+y)-20因式分解(2x-y)^2-8(2x+y)-20因式分解(2x-y)"-8(2x+y)-20=(2x-y)"-10(2
(2x-y)^2-8(2x+y)-20 因式分解
(2x-y)^2-8(2x+y)-20 因式分解
(2x-y)^2-8(2x+y)-20 因式分解
( 2x - y )" - 8( 2x + y ) - 20
= ( 2x - y )" - 10( 2x + y ) + 2( 2x + y ) - 20
= ( 2x - y )( 2x - y - 10 ) + 2( 2x + y - 10 )
= ( 2x - y + 2 )( 2x - y - 10 )
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
化简y(x+y)+(x+y)(x-y)-x^2
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
(x-y)²-8(x-y-2)
16-8(x-y)+(x-y)2
-8(y-x)^2×(x-y)
因式分解x(x+y)(x-y)-x(x+y)^2
(2x+y)²+(x+3y)(x-3y)-x(5x+8y)因式分解
[2(x-y)^5-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2[2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2]÷2(x-y)^2
【2(x-y)^3-8(x-y)^2(x+y)+6y(x-y)^2】/2(x-y)^2=
[(x-y)^2-(x+2y)(x-2y)]/y
计算:y-x分之x+y+x-y分之y-y-x分之2x-y
2x/(x-8y)(x+8y)-(x+8y)/ (x-8y)(x+8y)怎麼计算了 详细
化简(2x/(x+y)-4x/(y-x))/8x(x^2-y^2)得
x^2(x-y)+(y-x)
x(x-y)2-(y-x)3
【(x-y)^2+(x+y)(x-y)】除以 2x
