Question:expand entries

Hello everyone. I have a matrix M of 2x2 with numbers in its entries except a particular entry which equals to Im(a*t^2+b*t). I assume that t is real, so that the particular element that I mention obviously must expand to t^2*Im(a)+t*Im(b) but maple doesnt expand it (I use maple 11). I have tried the instruction

map(expand, eval(M)) assuming t::real

but it doesnt works. Could you help me with this, please
Thanks very much
Jorge
