If x is a negative integer, then (a) x+|x|=0 (b) x-|x|=0 x+|x|=-2x (d) x=-|x|

If x is a positive integer, then (a) x+|x|=0 (b) x-|x|=0 (c) x+|x|=-2x (d) x=-1|x|

If x is a negative integer, then (a) x+|x|=0 (b) x-|x|=0 (c) x+|x|=-2x (d) x=-|x|

If x is a positive integer, then x+|x|=0 (b) x-|x|=0 x+|x|=-2x (d) x=-1|x|

If x is a negative integer, then x+|x|=0 (b) x-|x|=0 x+|x|=-2x (d) x=-|x|

The factor of x^8 + x^4 +1 are (A) (x^4 + 1 - x^2), (x^2 +1 +x), (x^2 + 1 - x ) (B) x^4 + 1 -x^2 , (x^2 - 1 + x), (x^2 +1 + x) (C ) (x^4 - 1 + x^2, (x^2 - 1 + x), (x^2 + 1 + x) (D) (x^4 -1 + x^2), (x^2 + 1 - x), (x^2 + 1 +x)

f(x) = x^(x)+ x^(1/x), find f'(x).

If |(a +x,a -x,a -x),(a -x,a +x,a -x),(a -x,a -x,a +x)| = 0 , then x is equal to
