If x is an integer and (x)(x^4)(x^3) is positive, which of the following could be negative?	Choose the correct answer
A) x^4	B) (x)(x^3)	C) (x)(x)	D) x + x^11	E) 3x^2
A) X^4 - always positive (or 0).   B) X(X^3) = X^4 - Again always positive (or 0).   C) (x)(x) = X^2 - Again always positive (or 0).   D) x+x^11 - Could be -ve if x is -ve.   E) 3X^2 - again always positive (or 0)   Answer x + x^11.
