h(4) is 2(4)+3 which is 11
therefore g(11) is -4(11) = -44

By the binomial theorem, the
term in the expansion of
is
![\dbinom n21^{n-2}\left(-\dfracx4\right)^2=\dfrac{n!}{2!(n-2)!}\dfrac{x^2}{16}](https://tex.z-dn.net/?f=%5Cdbinom%20n21%5E%7Bn-2%7D%5Cleft%28-%5Cdfracx4%5Cright%29%5E2%3D%5Cdfrac%7Bn%21%7D%7B2%21%28n-2%29%21%7D%5Cdfrac%7Bx%5E2%7D%7B16%7D)
which suggests that the contribution of the binomial coefficient should make up the remaining factor of 21. That is,
![\dfrac{n!}{2!(n-2)!}=\dfrac{n(n-1)}2=21\implies n=7](https://tex.z-dn.net/?f=%5Cdfrac%7Bn%21%7D%7B2%21%28n-2%29%21%7D%3D%5Cdfrac%7Bn%28n-1%29%7D2%3D21%5Cimplies%20n%3D7)
