(1) k is greater than zero (2) k is an even integer
why exactly is it justified to go from asking whether the inequality equation is greater than zero to setting k = to 0? and assuming the factors are relevant? It seems to me that it\'s a bit of a stretch.
The question asks if the equation is greater than zero, not if its equal to zero. There is a distinction. For example, if we factor the left hand side of the equation we have (k+2)(k-1) = 0 so if k is equal to 1 or , -2 the equation is equal to zero. However, in order for the equation to be greater than zero, k cannot be 1 or -2. Those are not the solutions to (k+2)(k-1) > 0.
