   (x - 2)4 - (x - 2) = 0    and    x2 - kx + k = 0

have two roots in common.

 

3. Find all ordered pairs of integers (x, y) which satisfy x2 + 4x + y2 = 9.

 

4. The sum of the ages of the members of a family is currently 75 years, where the family consists of a mother, father, son, and daughter.  Six years ago, the sum of the ages of the family members was 53 years.  If the father is four years older than the mother, and the daughter is three years older that the son, find the current age of the father.
