Question 1032576: The area of a rectangular coffee table is given by the trinomial x2+7x−8. The table's length is x+8. What is the table's width? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Once again, we can long divide or just factor
x^2 + 7x - 8 = (x + 8)(x - 1)
so that the width has to be
x - 1
