" Q."3((i)/(2))quad 9x^(2)+6xy+y^(2)

Divide: (i) 5m^(2) - 30 m^(2) + 45m by 5m (ii) 8x^(2) y^(2) - 6xy + 10 x^(2) y^(3) by 2xy (iii) 9x^(2) y - 6xy + 12 xy^(2) by - 3xy (iv) 12x^(4) + 8x^(3) - 6x^(2) by -2x^(2)

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

Distance between the pair of lines represented by the equation x^(2)– 6xy +9y^(2)+ 3x - 9y -4 = 0 is

If x=2+3i and y=2-3i then find the values of : (x^(2)+xy+y^(2))/(x^(2)-xy+y^(2))

Solve (9xy + 7 xy + 9x ^(2)) + ( 8 + x ^(2) - xy - y ^(2) + 1).

Solve (9x+7xy +9x^(2)) + (8+x^(2) -xy -y^(2)+1) .

Factorise the following using appropriate identities: (i) 9x^(2)+6xy+y^(2) (ii) (ii) x^(2)-(y^(2))/(100)

Add 9x^(2) + 13xy + y^(2) and 6y^(2) - 2xy + 21x^(2)
