16(x+y)^2—25(x—y)^2因式分解16(x+y)^2—25(x—y)^2因式分解16(x+y)^2—25(x—y)^2因式分解16（x+y）^2-25（x-y）^2=[4﹙x＋y﹚＋5﹙x
16(x+y)^2—25(x—y)^2因式分解
16(x+y)^2—25(x—y)^2因式分解
16(x+y)^2—25(x—y)^2因式分解
16（x+y）^2-25（x-y）^2
=[4﹙x＋y﹚＋5﹙x－y﹚][4﹙x＋y﹚－5﹙x－y﹚]
=﹙9x－y﹚﹙9y－x﹚
16(x+y)^2—25(x—y)^2
=[4(x+y)+5(x-y)][4(x+y)-5(x-y)]
=(4x+4y+5x-5y)(4x+4y-5x+5y)
=(9x-y)(9y-x)
16—8(x-y)+(x—y)^2
2(x-y)/3—x+y/4=1 6(x+y)—4(2x-y)=16
x-y/x-x+y/y-(x+y)(x-y)/y² y/x=2
[(x+y)的平方—(x+y)(x—y)]除以2y怎么算
(12-2x)/X=(-16-2Y)/Y X^2+Y^2=25 Y
(1).(x-4)(x+1)+3x (2).(x+y)^2+12(x+y)+36 用多项式因分解
化简y(x+y)+(x+y)(x-y)-x^2
6x^2-xy-2y^2-4x+5y-2因试分解
(x+y)^2-16(x-y)^2
(x+y)^2-16(x-y)^2
分解因试..X平方-2XY-8Y平方-X-14Y-6
16-8（x-y)+(x-y)2
1.20y(2y-x)²与5x(x-2y)平方的公因式是—— 2.分解因式(x+y)(x-y)-(x+y)²
若x+y分之x-y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
若x-y分之x+y=3,求式子x+y分之5(x-y)—2（x-y）分之x+y的值
(x+y)(x-y)-(x-y)^2如题 (x+y)(x-y)-(x-y)^2
—2x+5(x+2y)—(x—3y) 3x+2(y-x)-(-x-4y) (x-2y)-(y-3—2x+5(x+2y)—(x—3y) 3x+2(y-x)-(-x-4y)(x-2y)-(y-3x)
【2(x-y)(x-y)(x-y)-8(x-y)(x-y)(x+y)+6y(x-y)(x-y)]/2(x-y)(x-y)
