| − | Let <math>P(x)</math> be a polynomial with rational coefficients such that when <math>P(x)</math> is divided by the polynomial <math>x^2+x+1</math>, the remainder is <math>x+2</math>, and when <math>P(x)</math> is divided by the polynomial <math>x^2+1</math>, the remainder is <math>2x+1</math>. There is a unique polynomial of least degree with these two properties. What is the sum of the squares of the coefficients of that polynomial?
