HI Jensen! Thank you for teaching us how to think mathematically. I have two questions maybe not the best questions lol . Is synthetic division a form of remainder theorem usage? Also is Rational Zero Theo the trick you thought us in grade ten to factor the cubic functions? like when you said after setting up the cross just divide both by the coefficient of x^3?

Thanks!

[@TheRealBlackKnight]

what about the f(x) = 2x^3 -mx+nx-2 divided by x+1 remainder is -12 and x-2

You can find that solution in the completed lesson on jensenmath.ca
I do that as an extension question with my classes.
