I got the formula (x/100 = 4x^2) for this correct, but I’m so confused about how to actually solve the resulting formula algebraically…. My instinct was to multiply both sides by 100 to get x = 400x^2. then set that equal to 0 so …
400x^2 - x = 0
…. did everyone then do the quadratic formula to get x =0.0025? is that the quickest way to roll?
