Perhaps you might show some steps? One approach is to expand, then show the form as Ax^2 + Bx + C. All quadratics can be written as the product of two factors, but not always with nice round numbers. It will not factor readily that I can see, so you might try using the quadratic formula if you must. Feasibility depends upon whether or not you allow radical quantities. Here's the form I am talking about:

(a^2+1)x^2 -a^2(a^2+2)x + (a^2+1)

I'll let you plug and chug.
