P2q2+pq–q3–p3 =

for p=0.5 and q = −0.5

!

In order to answer the question, we simply substitute the value of p and q to the given expression and solve. We do as follows:

P^2q^2+pq–q^3–p^3 
0.5^2(-0.5)^2+0.5(-0.5)–(-0.5)^3–(0.5)^3
-3/16 or -0.1875

Hope this answers the question. Have a nice day.
