Question 538707: help me solve +sqrt%282y%2B1%29-19=0+
Answer by KMST(5347) About Me  (Show Source):
You can put this solution on YOUR website!
+sqrt%282y%2B1%29-19=0+--->+sqrt%282y%2B1%29=19
Square both sides (keeping in mind that you risk adding extraneous solutions) to get
2y%2B1=19%5E2-->2y%2B1=361-->2y=360-->y=180
At this point you verify to make sure that you did not add an extraneous solution, but it's OK.
