I have an expression of the form a1xb1^2 + a2yc1^2a1*x*b1^2 + a2*y*c1^2
I want to extract the xx
and yy
from the expressions. a_,b_,c_a_, b_, and c_
are the only types of variables that appear in the expression . Form of xx
and yy
are not known. Anyone know how? xx
and yy
are not necessarily numbers .
