Many students in early algebra courses lose critical test and quiz points just because they haven't yet fully committed the Quadratic Formula to memory.
I recently came across a brilliant way to do so almost effortlessly ... a memory trick so sublimely ridiculous I couldn't help but think of the famous line: "This is so crazy ... it just might work."
(Sung slowly to the tune of "Pop Goes the Weasel")
"X is equal to negative B
Plus or minus the square root
Of B squared minus 4AC
ALL
Over 2A."
"X is equal to negative B
Plus or minus the square root
Of B squared minus 4AC
ALL
Over 2A."
Silly.
Effective.
Try it!
