(1 pt) This question is designed to test your ability to
formulate the correct try in the method of undetermined coefﬁ
cients. For each of the following equations you must enter the
correct try for a particular solution. The undetermined coefﬁ
cients must be the upper case letters P, Q, R, S, T etc. starting
at P and using as many as you need in order. If you need
three coefﬁcients, then use P, Q and R. If you need four coef
ﬁcients, then use P, Q, R and S. Answers with unnecessary co
efﬁcients will not be accepted. Also please note that Webwork
