The value of `( x-y ) ( x + y ) + ( y -z ) ( y + z ) + (z-x ) (z + x )` is equal to

What is x(y - z) (y + z) + y(z - x) (z + x) + z(x - y) (x + y) equal to ?

x y : y z : z x = 1 : 5 : 9 Find ( x + y ) : ( y + z ) : ( z + x ) = ?

What is the value of ((x - y)^3 + (y - z)^3 + (z - x)^3)/(9(x - y)(y - z)(z - x)) ?

The following steps are involved in finding the value of (a^(x+y))^(x-y)(a^(y+z))^(y-z)(a^(z+x))^(z-x) . Arrange them in sequantial order. (A) a^((x+y)(x-y).a^(y+z)(y-z).a^((z+x)(z-x)) (B) a^0=1 (C) a^(x^2-y^2).a^(y^2-z^2).a^(z^2-x^2) (D) a^(x^2-y^2+y^2-z^2+z^2-x^2)

What is ((x-y)(y-z)(z-x))/((x-y)^(3) + (y-z)^(3) + (z-x)^(3)) equal to ?

What is ((x-y)^(3) + (y-z)^(3) + (z-x)^(3))/(4(x-y)(y-z)(z-x)) equal to ?
