If pq = p^4 + q^2 – 2pq, for what value of q is pq equal to p^4 for all values of p? Choose the correct choice from the following answers
A) -2	B) -1	C) 2	D) 1	E) 0
C   p4 + q2 â€“ 2pq = p4   =&gt; q2 - 2=

0=&gt; q (q - 2p) = 0   =&gt; q = 0 or q = 2p   im not following the logic you used here.. how did you replace pq with 0 could someone help explain it in MOR0 D0TAI   0
