You can get rid of the brackets and try adding similar terms (remember that the second bracket has a minus sign in front of it so all its terms have to change signs when eliminating the brackets):

#17x^5+19x^2+15-9x^7+11x+17=#

#=17x^5+19x^2-9x^7+11x+32=# ordering the exponents:

#=-9x^7+17x^5+19x^2+11x+32#
