You can put this solution on YOUR website! log is assumed to be base 10 log(x^2+19) = 2 x^2+19 = 10^2 x^2+19 = 100

We are given x + y = 1. Cube both sides. You will get 1 = = + . Now replace by 19 ( ! given !) and replace (x+y) by 1 in the right side. You will get 1 = 19 + 3xy, which implies 3xy = 1 - 19 = -18. …
