Answer:
x=0 and -5
Explanation:
We can simplify this equation by moving the 3x over giving is
x²+5x=0 and then we can pull out an x since both parts of the left side have an x and we get
x(x+5)=0 now we can seperate them since they are multiplied and solve for X we get
x=0 and x+5=0 which when solved gets you x=-5
I hope this helps and please don't hesitate to ask if there is anything still unclear!
