I got the answer 1.92 and -11.92, am I correct?

mathmale · Answer

Please check your results by substituting them back into the original equation:   (v+5)^2 - 48= 0.  If you end up with a true equation, then your solutions are correct.

jhonyy9 · Answer

add to both sides 48 like a first step

mathmale · Answer

Starting with your v=1.92, I round that up to 2, and substitute that 2 into  (v+5)^2 - 48= 0.  that comes out to 7^2-48, which is close to zero.  Thus, I'd expect your v=1.92 is correct.  Check it by substition.
Please do the same with your v=-1.92.
