  1. ~ Bạn tham khảo ~
    (20x^4y-35x^2y^2 – 3x^2y) : (5x^2y)
    = 20x^4y : 5x^2y – 35x^2y^2 : 5x^2y – 3x^2y : 5x^2y
    = 4x^2 – 7y – 3/5

  2. ( 20x^4 y – 35x^2 y^2 – 3x^2 y ) : (5x^2 y)
    = ( 5x^2 y .4x^2 – 5x^2 y .7y – 5x^2 y . 3/5 ) : (5x^2 y)
    = 5x^2 y( 4x^2 – 7y – 3/5 ) : (5x^2 y )
    = 4x^2 – 7y – 3/5
