Answer :
Answer:
P=4-q
=> p³+q³+12pq = 64
=> (4-q)³+q³+12(4-q)(q) = 64
=> 64-q³+q³+(48-12q)(12q) = 64
=> 64+576q-144q² = 64
=> -144q²+576q = 64-64
=> 432q = 0
=> q = 0÷432
=> q = 0
=> p = 4-0
=> p = 4
Explanation:
=> p³+q³+12pq = 64
=> (4)³+(0)³+12(4)(0) = 64
=> 64 + 0 + 0 = 64
=> 64 = 64
=> LHS=RHS
