9(x-y)²+12(x²-y²)+4(x+y)² =[3(x-y)+2(x+y)]^2 =(5x-y)^2
(x²+4y²)²-16x²y² 因式分解
因式分解: 16(x-y)²-9(x+y)²
因式分解:4x²-y²-2y-1
求因式分解:(x²+y²)²-4x²y²,要用完全平方公式!
运用公式法:将下列多项式因式分解:(x²+y²)²-4x²y²
把(2z²-2x²-2y²)²-16x²y²因式分解
(3x-2y)²(3x-2y)²(9x²+4y²)²
因式分解:m³-2m²-4m+8;x²-2xy+y²-9
已知(x²+y²)(x²+y²-6)+9=0 ,求x²+y²
化简再求值[(x²+y²)²-4x²y²]÷(x²-y&su
3x²-4xy+y²
因式分解:16(x-y)²-9(x-y)² 用简便方法计算 202²-54²+2
