is there anyone who can help me recode to this to accept any form of the following equation please?

m=750/s

f = parseEquation(m3c.latex).differenceFunction(“s”,“m”)

correct:
isCorrect1

#equation m=750/s
isCorrect1 = f.evaluateAt(0,225) = 0 and f.evaluateAt(-4.5,0) = 0

disableEvaluation: true

showSubmitButton: true

submitLabel: “Check my Answers”

resetLabel: when m3c.submitted (when isCorrect1 “:white_check_mark:” otherwise “:cross_mark:”) otherwise “”
