One of them is correct, but idk why Im getting a second. Can anyone show me some workings for this?

When you square equations you add solutions

why are you squaring anything

#

i imagine you get a quadratic which gives you the two solutions

#

but since the quadratic is in terms of rootx you reject the negative solution

Hope you got the solution for this

Both work

In a sqrt graph it is impossible to obtain negative x values(excluded from the domain) by squaring we get 2 solutions but we must ensure it is greater or equal to 0
