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

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

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

9x^(2)+24xy+16y^(2)

Simplify: 2x^(2)+3xy -3y^(2)+x^(2)-xy+y^(2)

(3xy-2ab)^(3)-(3xy+2ab)^(3)=

If a=(x)/(x+y) and b=(y)/(x-y), then (ab)/(a+b) is equal to (a) (xy)/(x^(2)+y^(2)) (b) (x^(2)+y^(2))/(xy)( c) (x)/(x+y) (d) ((y)/(x+y))^(2)

Solve :a(x+y)+b(x-y)=a^(2)-ab+b^(2)a(x+y)-b(x-y)=a^(2)+ab+b^(2)
