(x²-4y²)-(x+2y)怎样因式分解?
(x²-4y²)-(x+2y)怎样因式分解?
(x²-4y²)-(x+2y)怎样因式分解?
(x²-4y²)-(x+2y)
=(x+2y)(x-2y)-(x+2y)
=(x+2y)(x-2y-1)
(x²-4y²)-(x+2y)
=(x+2y)(x-2y)-(x+2y)
=(x+2y)(x-2y-1)
(x²-4y²)-(x+2y)
=(x-2y)(x+2y)-(x+2y)
=(x+2y)(x-2y-1)
=(x-2y)(x+2y)-(x+2y)=(x+2y)(x-2y-1)
(x²-4y²)-(x+2y)
=(x+2y)(x-2y)-(x+2y)
=(x-2y-1)(x+2y)
(x2-4y2)-(x+2y)
=(x+2y)(x-2y)-(x+2y)
=(x+2y) [(x-2y)-1 ]
=(x+2y) (x-2y-1 )
因式分解 (x²+y²-1)²-4x²y²
求因式分解:(x²+y²)²-4x²y²
(x²+y²)²-4x²y² 因式分解
(x²+4y²)²-16x²y² 因式分解
分解因式:(x²+y²)²-4x²y²
分解因式:4b²c²-(b²+c²-a²)² 25(x+y)²-16(x-y)² x²-6x+9
怎么算啊这个:X²+4X+Y²-2Y+5=0 则X²+Y²=?²²²²²²²²²²²²X²+4X+Y²-2Y+5X=0 则X²+Y²=?
-x²/4+y²/9;因式分解
4x²y-xy²
9(x-y)²+12(x²-y²)+4(x+y)² 因式分解
已知(x+y)²;=8,(x-y)²;=4,求x²+y²
计算x²-x/x²×x/1-x和x²-4y²/x²+2xy+y²÷x+2y/x²+xy
x²+ y ²=4x 求x² + y ²的最大值,最小值
x²-4y²/x²+2xy+y²÷x+2y/2x²+2xy
1.(x+y)²-4xy=( )²2.x²-( )+25y²=( )²3.x²-8x²y²+16y四次方=( )²4.7.2²-2.8²= .
计算:4xy²-3x²y-{3x²y-[2xy²-4x²y+2(x²y-2xy²)]急
化简再求值[(x²+y²)²-4x²y²]÷(x²-y²)其实,x=2,y=2/3.
14x²-2y²是4x²-y²的几倍?
