    Bài 3:

    a) 3x – 9 = 3( x – 1 )

    b) 5x² – 10x = 5x( x – 2 )

    c) 6xy – 12x² – 9x²y² = 3x( 2y – 4x – 3xy² )

    d) 2x( x + 1 ) – 3y( x + 1 ) = ( x + 1 )( 2x – 3y )

    e) 3x( x – y ) + 2y( y – x ) = 3x( x – y ) – 2y( x – y ) = ( 3x – 2y )( x – y )

    f) y – 2 + 3x( y – 2 ) = 1( y – 2 ) + 3x( y – 2 ) = ( y – 2 )( 1 + 3x )

    g) 5x( x – 3 ) – x + 3 = 5x( x – 3 ) – 1( x – 3) = ( 5x – 1 )( x – 3 )
