Factorize: 4(x-y)^(2)-12(x-y)(x+y)+9(x+y)^(2)

Factorize: 4(x-y)^2-12(x-y)(x+y)+9(x+y)^2

If (3)/(x+y)+(2)/(x-y)=2 and (9)/(x+y)-(4)/(x-y)=1 then what is (x)/(y) equal to ?

Factorize following experssions (i) x^(4)-y^(4)" (ii)"9a^(2)-(2x-y)^(2)" (iii)"4x^(2)-9y^(2)-6x-9y

Factorize following experssions (i) x^(4)-y^(4)" (ii)"9a^(2)-(2x-y)^(2)" (iii)"4x^(2)-9y^(2)-6x-9y

Prove that the radi of the circles x^(2)+y^(2)=1x^(2)+y^(2)-2x-6y=6 and x^(2)+y^(2)-4x-12y=9 are in arithmetic progression.

2.If "3/(x+y)+2/(x-y)=2 and 9/(x+y)-4/(x-y)then

If x=2 and y=4, then ((x)/(y))^(x-y)+((y)/(x))^(y-x)=4(b)8(c)12(d)2
