Find the value of n if the coefficients of \(x^3\) and \(x^4\)are equal in the expansion of \((2x+1)^n\).
I rewrote bc i have a pet peeve where i don't like it when the LaTeX is wrong
it's nothing personal
@ur first question
it has already been answered here
https://web2.0calc.com/questions/what-is-the-value-of-the-modulus-of-6-4i_1
\(x^2-ax+2016=0\)
fixed your LaTeX
(it was kind of weird to read)
i didn't figure out the question but maybe try finding patterns
hope that helps
maybe this will help but as u can see in the url the numbers are different
https://www.quora.com/The-sum-of-two-numbers-is-8-and-their-product-is-15-What-is-the-sum-of-their-reciprocals
maybe this will help but it only involves when no 2 adjacent houses can be the same color:

just multiply each case and divide by the repeating numbers
does that help?
it might not help if you don't know a lot about counting and probability.
Thanks a lot!
