I have an equation for the relation between viscosity and temperature of a fluid, and I need to find the values of a0, a1 and a2 for the following equation:

The following data must be used for the same:

Could someone tell me how this can be done? I tried using the solve(eqn,vars) method, but that did not work.

Thanks in advance!!!
