Answer 1

Answer:

hi dear

Step-by-step explanation:

by property u can solve this question ,

the property use in the this question

a³+b³= (a+b) (a²+ab+b²)

p³+q³= ( p+q) ( p²+p×q +q²)

take comman ...

= p+q ( p+q)

hence solve....

Answer 2

p+q=0

=>p³+q³=0

EXPLANATION:

-------------------

(p+q)³= p³+q³+3pq(p+q)

=>p³+q³=(p+q)³-3pq(p+q)

since p+q=0

=>p³+q³=(0)³-3pq(0)

=>p³+q³=0
