Hi,

How would you solve the following - i'm stumped!

1. For every positive integer n, the function h(n) is defined to be the
product of all even integers from 2 to n inclusive. If p is the smallest
prime factor of h(100) +1, then p=?

2. In the xy-plane, at what 2 points does the graph of y = (x+a)(x+b)
intersect the axis?
1) a+b=-1
2) the graph intersect the y axis at (0, -6)
