Question 902829: (sqrt3x+1 - sqrt2x-1 = sqrtx-4)
I have looked at similar ones to try and figure out how to work it, BUT all of the similar ones have an PLUS between the first part of the equation, while this one has a MINUS sign. I have worked, reworked, and reworked this equation and again for the past 2 nights. I do not know what I am doing wrong. According to the book, the answer is suppose to be 5. I've plugged 5 back into the original equation and it is the right answer, but HOW am I suppose to get it? I'm completely stumped.

Question 907453: My professor is impossible to understand so I have been trying to self-teach. Currently we're working on radicals with multiple variables to different variables but no numbers. He wants us to reduce each variable to a single exponent. I have been able to get the correct answers when working with single variables and often get the exponent for Y correct but not X when working with multiple variables. I guess what I am asking is what is this called and where can I find examples? Everything I find regarding radicals includes numbers and is looking to reduce them to like _^5 sqrt4 rather than x^n Y^n which is the solution I am expected to give. Any help would be appreciated
