The factorization of `a(x + y + z) +b(x + y + z) + c(x + y + z)` is ​

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

If x+y+z=0 prove that |a x b y c z c y a z b x b z c x a y|=x y z|a b cc a bb c a|

If x % of a is the same as y % of b , then z % of b is a.(x y)/z % of a b. (y z)/x % of a c. (x z)/y % of a d. none of these

(x + y) ^ (3) + (y + z) ^ (3) + (z + x) ^ (3) -3 (x + y) (y + z) (z + x)
