The problem comes when we multiply both sides through by 0. We find
in the first case that 0 * j = 1 and in the second case that
0 * 2j = 2. So far, so good. But multiplication is supposed to be
"associative". If you multiply (a*b) * c you should get the same
answer as a * (b*c). For example, we can write 2*3*4 without
specifying which multiplication is done first, because (2*3)*4 = 6*4
= 24, and 2*(3*4) = 2*12 = 24. We get the same answer both ways.
It doesn't really answer your question, but may help you find an answer...

just multiply them together then factor (or factor first if that is easier to see)
sqrt7 * sqrt14 = sqrt7 * sqrt7 * sqrt2 = 7 * sqrt2
