The instruction on this problem had me totally lost for hours. m^6-4m^3-5 They went over U-Substitution as a method but didn't know why the answer was: (m^3-5) (m+1) (m^2-m+1) This video was a life saver!!!
It would be very helpful if you could put the lessons related to each other in a separate list so that we can watch them in a step-by-step manner and avoid confusion.
How I do it the other way? By starting ONLY with a³ - b³, obtaining at the end (a - b)(a² + ab + b²). Is it possible? Or only in the way you do it in the video?
@@myopiniondoesntmatterbut4826 Area models are a popular (and visual way) to do multiplication. You can look up things like "the area model of multiplication," "the lattice method of multiplication (short-hand form of the standard area model of multiplication)," and "factor sum or difference of cubes with area model." Take the time to do some research.
