So we just have to say, when does x, let me do this in a different color. We just have to think about when does x equal x squared minus 2x? Equal x squared minus 2x. When are our two functions equal to each other? Which is equivalent to, if we just subtract x from both sides, we get, when does x squared minus 3x equal 0? We can factor out an x on the right-hand side. So this is going to be, when does x times x minus 3 equal 0?
