" 24."ab(x^(2))+y^(2))-xy(a^(2)+b^(2))

Factorise : (vi) ab (x^(2) + y^(2) ) - xy (a^(2) + b^(2) )

Factorise: ab (x ^(2) + y ^(2)) - xy (a ^(2) + b ^(2))

Fractorise: ab (x ^(2) + y^(2) ) + xy (a^(2) + b ^(2)).

If (x+1)/(x-1)=(a)/(b) and (1-y)/(1+y)=(b)/(a), then the value of (x-y)/(1+xy) is (2ab)/(a^(2)-b^(2)) (b) (a^(2)-b^(2))/(2ab) (c) (a^(2)+b^(2))/(2ab) (d) (a^(2)-b^(2)backslash)/(ab)
