# What is a Binomial Coefficient?
First, let’s start with a binomial. A binomial is a polynomial with two terms typically in the format $$(x + y)$$.
A binomial coefficient is raising a binomial to the power of n, like so $$(x + y)^n$$.
We all remember from school that $$(a + b)^2 = a^2 + 2ab + b^2$$ but what if I wa... | HuggingFaceTB/finemath | |

We have to solve (x + 2)/6 = 3/(x - 1) for x.
(x + 2)/6 = 3/(x - 1)
=> (x + 2)(x - 1) = 3*6
=> x^2 + 2x - x - 2 = 18
=> x^2 + x - 20 = 0
