Correct. I got those answers. The root that did not work is the extraneous root.

Answer 4

can u check this one as well? http://prntscr.com/9gbit8

Answer 5

This is correct although I think a step is missing.

Between the x^2 -5x = 0 and the x = 0, x = 5 steps, I would add info on how I got the x = 0 and x = 5.

The flow would go like this:

x^2 - 5x = 0
x(x-5) = 0
x = 0 or x - 5 = 0
x = 0 or x = 5

It is your decision as to whether that is necessary to show.

As the work is, it is fairly obvious that x = 0 and x = 5.
