64x²y²%(4xy+16x²)²因式分解

64x²y²-(4xy+16x²)² =(8xy)²-(4xy+16x²)² =(8xy+4xy+16x²)(8xy-4xy-16x²) =(12xy+16x²)(4xy-16x²) =4x(3y+4x)*4x(y-4x) =16x²(3y+4x)(y-4x)

只能提取公因式 -16x²y²+12xy³z-4xy =-4xy(4xy+3y²z+1) 如果你认可我的回答,请点击左下角的“采纳为满意答案”,祝学习进步!

(1) 6x4y2-12x3y+27x2y3 =3x2y·2x2y-3x2y·4x+3x2y·9y2=3x2y(2x2y-4x+9y2) (2)-x4y+x3y2-x2y3=-(x4y-x3y2+x2y3) =-(x2y·x2-x2y·xy+x2y·y2) =-x2y(x2-xy+y2) (3)xn+3xn-1+xn-2=xn-2·x2+xn-2·3x+xn-2·1 =xn-2(x2+3x+...

(1)原式=abc(a-1)(4分);(2)原式=(4x+3y)(4x-3y)(4分);(3)原式=2(x2-2xy+y2)(2分)=2(x-y)2(4分);(4)原式=ab+a+b+1=(a+1)(b+1)(4分).

(1)(X²+4Y²)²-16X²Y² =(X²+4Y²+4XY)(X²+4Y²-4XY) =(X+2Y)²(X-2Y)² (2)(a²+1)²-4(a²+1)+4 =(a²+1-2)² =(a²-1)² =(a+1)...
