Thermal physics question...

A wire resistance thermometer is constructed with material that has a resistance that varies as temperature as below.

R=R0 (1+ alphaT + betaT^2)

where constants alpha and beta are 3.8 x 10^-3 k^-1 and -3.0 x 10^-6 k^-2 respectively.

Calculate the temperature measured on the resistance scale at 70 degrees C on the ideal gas scale.

I've got no idea where to start on this one, any ideas?

Thanks, Rob.
