You can put this solution on YOUR website!
first, you write radical (of x) symbol like this:
sqrt(x), than you put +in+front+and+ after sqrt(x) and you will get a symbol
sqrt%28x%29...the "square root function"

sqrt%283w%2B4%29+=sqrt%287w-12%29...if square root of two numbers or expressions are same, than these numbers or expressions are same too; so, you will have
3w%2B4=7w-12
12%2B4=7w-3w
16=4w
16%2F4=w
highlight%284=w%29
