It seems you might be referring to the Binomial Theorem, which is often associated with Sir Isaac Newton. The Binomial Theorem provides a formula for expanding expressions of the form \((a + b)^n\), where \(n\) is a non-negative integer.
The theorem states that:
\[
(a + b)^n = \sum_{k=0}^{n} \binom{n}{k} a^{n-k} b^k
\]
In this equation:
- \( \binom{n}{k} \) (read as "n choose k") is the binomial coefficient, calculated as:
\[
\binom{n}{k}
