Set both factors equal to 0 and solve. n+1 = 0, n = -1 n+9 = 0, n = -9 n= -1, -9 3/22/2013 | Aaron G. Comment

The question is asking, For what values of n will the equation equal zero. So you can break it apart and set each set of parenthesis equal to zero then solve for n. => n+1=0 , n+9=0 so the values of n that make the equation zero are -1 and -9. 3/22/2013 | Christopher K. Comment
