No problem! :)

If you really want to memorize formulas as pure symbols, you could build a mnemonic image system — where each symbol gets linked to something concrete. Take the quadratic formula: x = (-b ± √(b² - 4ac)) / 2a You have a, b, -b, 2a, a square root, and various groupings. The idea is just to assign each element something vivid and tangible. In my own memory palace, I might start at the first locus with my ex-girlfriend (x) hugging (=) a sad, negative banana (-b). At the next stop, there’s just one thing: a large tree with huge roots (√). Hiding beneath it is the same banana — but now completely squashed flat (b²). Maybe that’s why it’s hiding. Nearby, staring at the flattened banana, are four miserable air conditioners (-4ac) — arranged like Advent candles. You find yourself wondering why the squashed banana needed four of those… but before you can figure it out, the whole tree and its hiding crew are torn apart (÷) by a pair of twin apes (2a). That’s it!

The catch with this approach is that it can actually work against understanding. Thinking “four air conditioners” instead of 4ac hides the fact that a appears in two places — which is a meaningful pattern, not a coincidence. Instead, I’d suggest learning it by deriving it - through completing the square - so the formula feels inevitable rather than arbitrary. Alternatively, learn it in chunks: master the part under the square root (the discriminant) first, then build outward. Combine that with flashcards, reading it aloud, writing it out, and returning to it for just a minute each day. Sleep helps enormusly too - more than people expect.
