Question 60914: I can only solve part of this equation and then I get stuck. Can someone show me the next steps I need to take and explain how they are done? I have done the equation as far as I can:
SQRT(2X-1)+SQRT(X-4)= 4 <----original equation
SQRT(2X-1)=4-SQRT(X-4)
(SQRT<2X-1>)^2 = (4-SQRT)^2
2X-1 = (4-SQRT)(4-SQRT) <------I am lost as to how to solve finish this side of the equation.
Thanks!

3____
√[6] – √[3]
3 * √6+√3
√6-√3 √6+√3
= 3√6 + 3√3
√36 + √12 - √12 -√6
=3√6 +3√3
6-3
=3√6 +3√3
