Best ResponseYou've already chosen the best response.1So we see that the left side and the right side are identical so the equation is true of all values of x that are greater than or equal to 0

Best ResponseYou've already chosen the best response.0why did you add a negative sqrtx to the left? and I am trying to solve for x, not prove that it is true.

Best ResponseYou've already chosen the best response.1I wanted the denominator on the left to be the same as the denominator on the right so I multiplied numerator and denominator by 1

Best ResponseYou've already chosen the best response.1And I did solve for x. x is all real numbers greater than or equal to 0. Just because there are many solutions does not mean the problem is not solved.

Best ResponseYou've already chosen the best response.1It's sort of like if you have to solve an equation such as: x+3 = x+3 That is true for all real numbers.

Best ResponseYou've already chosen the best response.0Okay, I guess I was thinking that I had to isolate x and get an actual value. But thank you!!

Best ResponseYou've already chosen the best response.0wait, on the right, where did the extra sqrtx come from?

Best ResponseYou've already chosen the best response.1Had to rewrite the number 1 as: \[\frac{\sqrt{x}1}{\sqrt{x}1}\]

Best ResponseYou've already chosen the best response.0so where did the extra sqrtx come from, though?
