1. The problem statement, all variables and given/known data x = x(8-2x) 2. Relevant equations x = x(8-2x) 3. The attempt at a solution My Solution x = x(8-2x) 1 = 8 - 2x 2x = 7 x = 7/2 Provided Solution x = x(8-2x) x = 8x - 2x^2 2x^2 -7x = 0 x(2x - 7) = x = 0 / x = 7/2 Is my approach wrong? Is x=0 always a possible answer, in addition to the found solution, so, should I have simply included x=0 in my solution? Thanks!
