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!

Answer:

x = 0 or x = -5

Explanation:

Solve for x over the real numbers:

x^2 + 8 x = 3 x

Subtract 3 x from both sides:

x^2 + 5 x = 0

Factor x from the left hand side:

x (x + 5) = 0

Split into two equations:

x = 0 or x + 5 = 0

Subtract 5 from both sides:

Answer: x = 0 or x = -5
