Great pace for fast and dirty review. Would recommend in linear equations with fractions, first multiply all terms by LCD (least common denominator) to get rid of the fractions to lessen the chance of simple math errors, as in 4b of linear equation review.

[@Misslayer99]

Yeah I knew I wasn't crazy. He got it wrong too, and then made a "correction" with the same mistake

[@trustlaks]

Excuse me, I love your content but at @ 13:15 you wrote 6/15 + 5/15 = 21/15 rather than 11/15. This change equates the final answer to x=4

[@MOTV583]

You're correct. The answer is x=4. I worked on this problem multiple times because I kept getting x=4. I thought I did something wrong because I solved it a bit differently by eliminating the fractions when I multiplied all of the terms by the LCD, which is 15. I thought I did something wrong. Finally, I just plugged it into my calculator, and the answer is x=4. When you plug 4 in for X you will get -2/3 on both sides. All that aside, great content. It is a lot of work to go over so much material in two and a half hours. Small mistakes are to be expected, and we can still learn from the small errors. Thank you, I appreciate everything you've done.

This is a very good video which gave me a good revision on my fundamentals. However there were a lot of basic calculation errors during the "Polynomial Review" section (basically the later half of the video) of the video which completely influenced the answer. An instance would be in 2:11:19, you would factor by 2x^2 not 2x thus the answer would be (x+9) (2x^2-5). I assume Brian was super tired while filming this video. Watch out guys your calculation are not wrong :)
