In addition to showing work (or at least telling us what you find difficult about this), so we know what sort of help you need, you might want to explain its meaning. Do the symbols that look like * and x both mean multiplication, or something else?

But the basic idea of algebra, when the variable of interest appears only once, as here, is just to undo one operation at a time, starting on the outside (the squaring), and moving inward (division and multiplication). Have you tried doing that? What happened?
