Question 177205: Good day to all of the tuitors here. iam just hopeful that my math homework might be solved by one of them. I actually have a little knowledge about conjugate of radical expressions but i have doubts if my final answer is correct. The problem goes like this....... Simplify the square root of x over 2x+1. Now in my try out of answering this question, my answer is square root of x times 2x-1 over 2x-1. Is that correct? pls help me. I need to know the correct answer or i will have trouble sleeping. Thanks to the tuitors. You guys have overwhelming answers.
