Subtract using horizontal method :
`5x^(2) + 7xy - 2y^(2) " from " 3x^(2) + 5xy + 2y^(2)`

Subtract using horizontal method : x^(3) - y^(3) + 2 " from " x^(3) +y^(3) + 3xy +1

Subtract : 2x^(2) + 3xy - 4y^(2) " from " 4x^(2) - xy +3y^(2)

Add the following expressions using horizontal method : -x^(2)y + xy^(2) + 2xy , 3x^(2) y + 4xy^(2) + 5xy and 7x^(2)y - 10xy^(2) - xy

Using horizontal method : Subtract -x^(2)+y^(2)+2xy " from " 2x^(2)-3y^(2)

Subtract : 7xy + 5x^(2) - 7y^(2) + 3 " from " 7x^(2) - 8xy + 3y^(2) - 5

Subtract : 5x^(2)-3xy -7y^(2) from 3x^(2)-xy-2y^(2)

Using horizontal method : Add x^(2)+y^(2)- 2xy , -2x^(2)-y^(2)-2xy and 3x^(2) +y^(2) +xy

Evaluate : 3x^(2) + 5xy - 4y^(2) + x^(2) - 8xy - 5y^(2)

Factorise : (iv) 5x^(2) - 4xy - 12y^(2)

How much more than 2x^(2) + 4xy + 2y^(2) is 5x^(2) + 10xy - y^(2) ?
