Multiply :
`3x^(2) y - 7xy^(2) +2xy" by " 4xy`

Multiply : -2x^(2) with 3xy

Multiply : 5x^(2) - 8xy + 6y^(2) - 3 by -3xy

Multiply 5xy^(2) xx(3x^(2) +2xy ) " by " 5xy^(2)

Multiply : -6x^(2) "with " -2xy

Simplify the following : 3xy^(2) - 5x^(2)y + 7xy - 9xy^(2) - 4xy + 6x^(2)y

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

Subtract : 5x - 3x^(2) + 8xy from 7x^(2) + 3xy - 4x .

Multiply : 3/7 x^(2) y^(3) and -14/15xy^(2)

Factorise : (ii) 3x^2 y - 6xy^2 + 9xy

Multiply : -3bx, -5xy and -7b^(3)y^(2)
