# Quotient Ring?

Algebra Level 5

Let $$\mathbb R[X]$$ be the polynomial ring of real coefficients. Then there exists some ideal $$J$$ such that the quotient ring $$\mathbb R[X]/J\cong$$:

1. $$(\mathbb R,+,\times)$$, the real numbers ring
2. $$(\mathbb C,+,\times)$$, the complex numbers ring
3. $$(\mathbb H,+,\times)$$, the quaternion ring
