Question

Having a problem with algebra (just a simple question that I should know the answer to, but I'm just having one of those days). Could somebody help?

Answer 1

The answer I marked is what I think is correct.

Answer 2

Hmm I had to Google it, I'm not really familiar with the term "radical equation" either.
It looks like it just means anything involving a `radical` on the x.

Examples:\[\Large\rm \sqrt x+2=7\]\[\Large\rm 4\sqrt x=24\]

Answer 3

So then it would be d instead of a?

Answer 4
