Natural Frequency 2 = 0.5(sqrt(5*(sqrt(129)-9)))

Note: In order to calculate the natural frequencies, the first matrix was simplified into a polynomial of degree 8. The poly() function was utilized ````poly(80 20 0 -4200 12000)```` to isolate the roots. The eig() function was utilized for the second, simplified matrix in order to isolate the eigenvalues for each natural frequency.
