Your videos are great. I'm a bored lawyer in my 50s and I'm resuming my deep dive into astrophysics. I watch your videos all the time to refresh my pre-calc skills.

x^18, common denominator isx^3 which gives ( x^9+x^12)/x^3

@danpost5651 Год назад

I got: x^8 - x^7 + 2x^6 - 2x^5 + 2x^4 - 2x^3 + 2x^2 - 2x + 2 - 2/(x+1) I was taught to simplify such that the degree of the polynomial in the denominator should always be greater than that of the numerator.

Do you reccomend a hiset science course? Your hiset math prep course was really good and helpful.

@danielmadden9691 4 месяца назад

I still am not sure why you can't get a common denominator by multiplying both bottom values, but I see how you got your answer John,I must be missing something

@charlesmitchell5841 Год назад

Good refresher. Sometimes you can forget high school math. Especially if it was a long time ago.

x7(1 + x2)/(x + 1) (x7 means x raised to the seventh and x2 means x squared). woulda been neater if the numerator in the original problem was x8 - x10!!

@thedailyclipper9008 Год назад

Can't we divide x8 + x10 by x²+X in numerator such that we can cancel out the denominator and quotient is answer .

@nuffroom863 Год назад

I got it but, as usual, doubted it to be the correct answer. Love watching your videos! Kinda see them as a daily maths puzzle.

@TuttifruttiNinja Год назад

Divide both by x so you've got (x^7+x^9)/(x+1) Then: X^7*(x^2+1)/(x+1) Which is: x^7*(x-1)*(x+1)/(x+1) (Binomial) So: X^7*(x-1)

Not watching the video though, no time

@myfavoritegames8805 Год назад

I got it right at first and you confused me.

@bobcornwell403 Год назад

I came up with x⁶ + x⁹.

This helped me. I got the answer wrong.❤🎉

@yeoldfart8762 5 месяцев назад

I'm starting to often know where you are going though not always my gut feeling that the answer always seems unfinished.. and unsatisfying. One never knows what x is .It seems that the only one satisfied is the teacher. Am I the only one that feels this way.

Warning! If you received a "gift" of a free Mac Pro or iPhone for getting the problem right, it will cost you several hundred US dollars in International Shipping and Customs fees, but you won't get a tracking number or a delivery ever. If you used a credit card you should cancel that card asap.

I like your videos but find you way too talkative. Plus every video has you introducing yourself again, and again, and again,... I really wish you would just get to it!
