x2-4y2+2x-4y分解因式
x2-4y2+2x-4y分解因式

x2-4y2+2x-4y分解因式
x²-4y²+2x-4y
=x²+2x+1-(4y²+4y+1)
=(x+1)²-(2y+1)²
=(x+1+2y+1)(x+1-2y-1)
=(x+2y+2)(x-2y)

x2-4y2+2x-4y
=(x+2y)(x-2y)+2(x-2y)
=(x+2y+2)(x-2y)

x" - 4y" + 2x - 4y
= [ x" - (2y)" ] + ( 2x - 4y )
= ( x + 2y )( x - 2y ) + 2( x - 2y )
= ( x + 2y + 2 )( x - 2y )

x2-4y2+2x-4y
=(x+1)²-(2y+1)²
=(x+1+2y+1)(x+1-2y-1)
=(x+2y+2)(x-2y)
