Answer 1

Answer 2

The equation can be rewritten as:
\[\sqrt{(x-5)^{2}}+12\sqrt{x}=15\sqrt{x}\]
Take the squareroot of the first part and then subtact the right hand portion form both sides to get a zero on right, then try your solutions

Answer 3

Start with \(x \ge 0\). You should ponder why this is so.

Simplify quite a bit \(\sqrt{(x-5)^{2}} = 3\sqrt{x}\)
Squaring, since everything is positive \((x-5)^{2} = 9x\)

Now, you have a plain, old Quadratic Equation. Remember that \(x \ge 0\)
