2y^(3)+2x^(2)-2y^(2)

List of the like terms in the following expression. (i) 4x^(4),-7x^(3),8x^(2),12x^(3),-9x^(4),-5x,4x^(3),12x^(2) (ii) 5xy,-3x^(2)y,2xy^(3),-2x^(2)y^(2),5x^(2)y,-3xy,6x^(2)y^(2)

If x:y = 3 : 2, then the ratio 2x^(2) + 3y^(2) : 3x^(2) - 2y^(2) is equal to :

Find each of the following products: (i) (4x + 5y) (4x - 5y) (ii) (3x^(2) + 2y^(2)) (3x^(2) - 2y^(2))

If x:y:z=2:3:4 , what is the value of ((x^(2)+2y^(2)+z^(2))/(3x^(2)-2y^(2)+4z^(2))) ?

If 7x - 15y = 4x + y , find the value of x: y . Hence, use componendo and dividendo to find the values of : (i) (9x + 5y)/(9x - 5y) (iI) (3x^(2) + 2y^(2))/(3x^(2) - 2y^(2))

Identify like terms in the following: x^(2),y3xy^(2)-2x^(2)y, 4x^(2)y^(2)
