Question 646028
 Solve the equation for t and use the rewritten equation to find
 an expression for the time it takes to travel a distance of (b3-6b2+9b+16)
 miles at a rate of (b+1)mph.
:
t = dist/rate
:
t = {{{(b^3-6b^2+9b+16)/(b+1)}}}
Use synthetic division here
......._______________________
 -1 |1 - 6 + 9 + 16
........1 - 1 + 7 - 16
........-----------------
........1 - 7 + 16 + 0
:
results from this t = (b^2 - 7b + 16) represents the time
