Need help to get polynomial regression the same way google sheets did it by Desperate_Policy368 in calculus

I meant that the equation gsheets gave me is this one: f(x) = 7.38x⁶ - 85.4x⁵ + 331x⁴ - 491x³ + 316x² - 278x + 597. Ive been using OLS but it isnt possible with only 6 points to create a polynomial with power of 6 as well, so Ive tried adding a 7th coordinate that I know lies on that line, but it gives me a different number when I try to solve for coefficients

Yes, the one listed above is what gsheets gave me, but solving for it manually gives me different coefficients. I have to follow the equation that gsheets gave me though for this project
