Hi, Any advice with the problem below would be greatly appreciated. X = √a + 1/√a + 1; X>0; express X - 2X in terms of a. btw, answer = a + 1 + 1/a; how do you derive it though? Thank you, Sean.

X-2X is just -X, please recheck the question.
Where you write "1/√a+ 1" do you mean (1/√a)+ 1 or 1/(√a+ 1)?
Hello, Seaniboy! . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Thanks for your help people. Apologies for the symbols in the question. I must use an 𝑥 instead of X next time!
Hi, I see what you mean. I am trying to find symbols to insert to make things a little clearer. In english it is X = √a + a fraction in the form of 1 over √a + 1. Thanks for having a look at the problem anyway.
