You are the best teacher I have ever seen, your explaination is breath taking. Thank you very much. 10 out of 10 👍

Sir. How did you find -12k and +5k… you lost me from that part.. actually why are you left with K to the power 2.. where did the the 2 go?? Cause I’m my understanding, Weren’t we supposed to cancel out both of the k’s that had a power 2 and remain with 2?

[TansonZulu]

How did you calculate 2k squared-k squared

[blessingsmuyunda]

I have understood the process but I don't know where you left that 2k raised to the two

Sir you don't even explain Where you got that 12k and 5k🙄. Me am lost from there where you introduced a 12 and 5

Hello Sir. Can you help me this question on Geometric progression word problem? Question- At an annual agricultural and commercial show event, 1200 people visited a stand on it's first day. Thereafter, the of number of show- goers visiting the stand fell by 10%, of the number on the previous day. (a) The show closed after 10 days. How many people visited the the stand at the close of the event?. (b) If the show had been kept open indefinitely, what would be the maximum number of people visiting the stand??

What if the first three terms of a geometric progression are 6+n, 10+n and 15+n .find the value of n

[Dannnykamuti]

4sure sir the value of 5k and 12k how?

[geraldchanda]

Thank now I know how to find the value of k

And I think there's an error there the answer was supposed to be 10
