# Algebra/Simple but puzzling

Question
What is x^2=4x and please include steps so I can help my classmates later, because none of us know.

If the equation is x^2 = 4x, that is the same as what is gotten when 4x is subtracted from both sides.  Doing this gives x^2 - 4x = 0.

An x can be factored out, giving x(x-4) = 0.

Once the equation is in this form, it can be seen that we need x=0 or x-4=0.
The 1st one is at x=0 and the 2nd one is at x=4.
