He is a great teacher... but I'm having similar problems as I did back in high school ha. I hear a lot of "well I want this X over here so I'll bring that over there and decide to take that fraction and send that to the top and bring over another X." I just can't understand where all this random "toss ups" seem to come from. There must be lots of rules I'm not familiar with yet? I suppose get lost when the algebra comes into the lecture
Difference of perfect squares is a College Algebra technique. Surely it's touched in a high school Algebra class as well, but it just something you should recognize. If you have "something" squared minus "something else" squared you can ALWAYS factor it into: ("the square root of something" minus "the square root of something else")("the square root of something" plus "the square root of something else") For example, Factor: (x^2 - 16) Ans: (x-4)(x+4) Another Example: Factor: (36 - y^4) Ans: (6 - y^2)(6 + y^2)
excellent! i forgot this video existed : )

U would be graet math teacher
Great*
Idk but i'm bad at math and it is fraction
5:34 - 7:15 what the hell are you talking about?
