" (i) "9x^(2)+6xy+y^(2)

Show that the equation 9x^(2) - 6xy + y^(2) + 18x - 6y + 8 = 0 represents a pair of lines. Find the acute angle between them.

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

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

If ((5x-y))/((5x + y)) =3/7, what is the value of ((4x ^(2) + y ^(2) -4 xy ))/( ( 9x ^(2) + 16 y^(2) + 24 xy)) ?

Factrorise the following using appropriate identities. 9x^(2)+6xy+y^(2)

The acute angle between the line represented by 9x^(2)-6xy+y^(2)+18x-6y+8=0 is

Show that the following equations represents a pair of parallel lines and also find the distance between them. 9x^(2)-6xy+y^(2)+18x-6y+8=0
