Factorise the following using appropriate identities : (i) 9x^(2)+6xy+y^(2) " " (ii) 4y^(2)-4y+1 " " (iii) x^(2)-(y^(2))/(100)

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

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

Distance between the lines represented by 9x^(2)-6xy+y^(2)+18x-6y+8=0, is 1(1)/(sqrt(10))2*(2)/(sqrt(10))3*(4)/(sqrt(10)) .sqrt(10)5.(2)/(sqrt(5))
