Im not sure how to prove this. Maybe i can show that IJ is bigger than K, and show a counter example where something is in IJ but not in K? but not sure how to do this either.

Hint:
For example, $;p(x)=4x^2+2xin IJ;$ , yet $;p(x)notin K;$ . Try to prove this.

But aren't the polynomials in I zero?

@H.B What? The polynomials in $;I;$ are all those polynomials that vanish at zero, not only the zero polynomial...
