Thank you sir for making.. Tomorrow is my IDS Exam..And i completely understood how to solve the polynomial regression problem..
This video helped a lot..

Thank you for your explanation sir. We'll understood. Isn't the third equation first variable be (y x^2) 27.5*135=3712.5

I'll sub when you get it right

Is your last datapoint 7,11.5 or 7,12? You switched it after minute mark 0:30. I suppose you intend 11.5 since your yx result shows 80.5 instead of 84

HI Dr
there's no links for the other examples

Sir matrix kase solve kya hai

How did we get a0,a1,a2 value

[@yahiagamal937]

it is math, generally, if u have 2 unknowns, u will need 2 equations,
3 unknown, 3 equations
4 unknowns, 4 equations, and so on.
A simple example that u can give u understanding of getting knowns from equations:
x+y=1 -----(1)
2x+y=2-----(2)
from (1), y = 1-x -----(3)
put (3) in (2)
2x+(1-x)=2,
2x+1-x=2,
x+1=2
then x = 2/1 = 2 -----(4)
put (4) again in (1)
(2)+y=1,
y=1-2,
then y = -1
Now apply this concept in a0,a1,a2 . it will take more time because they are 3 unknowns, but you will get them in the end.
Good luck
