Question Solution:

Degree of a differential equation is the power of its highest order derivative after the differential equation is made free of radicals and fractions if any, in derivative power.

Hence, here the degree is 1, which is power of

The augmented matrix for this system is



Using Gauss-elimination method we get





Now, for infinite solution last row must be completely zero

i.e.&α - 2 and &β - 7 = 0

=> &α = 2 and &β = 7
