abstract = {From the text: I set my year 12 further mathematicians a deceptively simple question as a starter. Prove $1+\sqrt{3}$ is a solution of the quadratic equation $x^2-4x+2\sqrt{3}=0$ and hence, or otherwise, find the other solution in its simplest exact form. The first part presented no difficulty, but I was a little disappointed that no one spotted the efficient way to tackle the second part.},
