Question

Evaluate (p^2 + q^2)x = pq

Answer 1

Answer:

x = pq/(p^2 + q^2)

cause i don't see any other options here

Answer 2

Answer:

p2−q2)/(p2+q2) , dividing both numerator and denominator by q2,

= [p/q)2−1]/[(p/q)2+1]

=[(x+3/x−3)2−1]/[(x+3/x−3)2+1]

=[(x+3)2−(x−3)2]/[(x+3)2+(x−3)2]

= 12x/(2x2+18)

=6x/(x2+9)
