Question 711925: I've been told to solve this by using the Zero Product Property.
1.) 5b^2 + 9b = 0
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
5b^2 + 9b = 0
b(5b + 9) = 0 ... factor
b = 0 or 5b+9 = 0 ... using the Zero Product Property here
b = 0 or 5b = -9
b = 0 or b = -9/5
The two solutions are b = 0 or b = -9/5
