Question

what is If p + q = 12 and pq = 22, then find p power2 + q power 2

Answer 1

Answer:

100

Step-by-step explanation:

p+q = 12

pq = 22

(p+q)² = p² + q² + 2pq

(12)² = p²+q²+44

144-44 = p²+q²

100 = p²+q²

Answer 2

Answer:

100

Step-by-step explanation:

p+q= 12 and pq= 22

We know the identity that

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

12^2 = p^2+q^2+2(22)

144 = p^2+q^2 +44

144-44 = p^2+q^2

Hence p^2 + q^2 = 100
