Draw a function by only using two input NOR gates T = (BD + A'BC'+A'CD)

How can i draw this by only using NOR-Gates? This is what i have done so far:

Have I understood this right?
Yes, looks like you understood the question correctly and are implementing only using NOR-gates. 

I also see correct usage of DeMorgan's Theorem.

Your answer seems to be correct. Good luck!
