Answer:

Two solutions

Explanation:

x(x+2)=0 has two solutions.

x(x+2)=0

x² + 2x = 0

The "x²" can be a good indicator there will be two solutions since it is being "squared" and is been risen to the power of two.

-> We can also see this with graphing, see attached

-> Need to know the solutions? We can find them by solving for looking at the graph, they are x = -2, 0
