Question 969322: I did this problem but I still do not have the answer.

Find all solutions to the equation.

5b2 + 20b = 0

b = 0 or b = −4
only b = 4
b = 0 or b = 4
b = 0, b = 4 or b = −4
only b = −4

Whatever gave you the idea that ?



So 4 is most certainly not an element of the solution set to the equation



Divide both sides by 5
