Question

Resolve into factors :

p⁴+q⁴+p²q²​

Answer 1

p4+q4+p2q2

p4+q4+2(p2q2)-p2q2

(p2+q2)2 -(p2q2)2

(p2+q2)2-(pq)2

(p2+q2+pq)(p2+q2-pq)

You got your answer

Answer 2

Answer:

p⁴ + q⁴ + p²q²

= (p²)² + (q²)² + 2p²q² - p²q²

= (p² + q²)² - p²q²

= (p² + q)² - (pq)²

= (p² +q² + pq)(p² + q² - pq)
