Question

how would you solve: (square root 3x+4)-( square root 2x-4)=2

Answer 1

start with
\[\sqrt{3x+4}=2+\sqrt{2x-4}\] and then square both sides

Answer 2

that will give you
\[3x+4=4+(2x-4)+4\sqrt{2x-4}\] now put everything without a radical on the left and square again

Answer 3

you get
\[x-4=4\sqrt{2x-4}\] before you square

Answer 4

if you square the right you would have to foil right?
