1.  x^2+5x+6 = (x+3)(x+2), which implies that the sides could be x+3 and x+2.  (There are theoretically an infinite number of side-lengths, though--in general, for any polynomial or reciprocal of a polynomial P(x), \frac{x+3}{P(x)} and P(x)(x+2) is valid.  However, the set provided makes the most sense.)

2.  Profit is the difference between cost and revenue.  For revenue, 0.0000x^2 = 0, so revenue equals 40x, so profit equals 26x-120,000.
