Homework Statement

The question states
Use a change of time variable to show that the equation
can be reduced to the diffusion equation.
The Attempt at a Solution
I've tried a couple of things, primarily setting up

If anybody wants to give me a pointer as to what I should be looking for, it would be appreciated.
Thanks.
