Best ResponseYou've already chosen the best response.1Like the last one, get 5sqrt(x) by itself on one side of the equation, and then square both sides.

Best ResponseYou've already chosen the best response.1You can do it either way actually. I find it simpler to square both sides at that point so you don't have to deal with fractions. Those fractions would cancel out later anyway, so no need to introduce them in the first place.

Best ResponseYou've already chosen the best response.0(x−6)^2 is (x6)*(x6) use foil or whatever method you prefer.

Best ResponseYou've already chosen the best response.1Just as an FYI, here's another way to look at squaring a square root: Note that: \[\LARGE (X^{S})^{T} = X^{ST}\] \[\LARGE \sqrt{x} = x^{1/2}\] \[\LARGE (\sqrt{x})^{2} = (x^{1/2})^{2}=x^{(1/2)(2)} = x^{1}\]

Best ResponseYou've already chosen the best response.1\[x6=5\sqrt{x}\] \[(x6)^{2}=(5\sqrt{x})^{2}\] \[(x6)(x6)=25x\] \[x(x6)6(x6)=25x\]
