Best ResponseYou've already chosen the best response.0Ok so 2x^2  1 has solutions 2x^2 = 1 2x^2 = 1/2 sqr(x^2) = sqr(1/2) ok I am stuck here to finding the solutions

Best ResponseYou've already chosen the best response.2Thats not right .. if you were to sqrt the 2 and then you'd be left with \[(\sqrt{2}+1)(\sqrt{2}1)\] diffrence of squares ..
