I'm not getting the correct demand function? I always keep getting off by a bit and really confused here

2. , Suppose a person has a utilityr function U(.1'1, 1'2) = :E'f+r , which she maximizes subject to her budget constraint, 30:51 + ng = m, where p.q.m are all positive. Use the Lagrangian method to solve the maximization problem, and nd the demand functions for the consumer. Show that the demand functions are homogeneous of degree zero in prices (p,q) and income (m)
