Assuming you mean this:
x^2 + 5x = 0
x(x+5) = 0
x=0, x+5=0
x=0, x= -5
{-5,0}

It seems you mean x^2 + 5x = 0.
Therefore, x ( x + 5 ) = 0
which gives x = 0 or x = -5
Answer: { -5, 0 }

factor out x
x (x + 5) = 0
x = 0 or -5

x² + 5x = 0
x(x + 5) = 0
x = 0
x = -5
so {-5,0}

x2 = - 5x
Removing x from both sides
x = -5
or x = 0
