Question

if p+q= 12 and pq=22 then find p2+ q2​

Answer 1

Answer:

if p+q= 12 and pq=22 then find p2+ q2

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

=. 12×12

=. 144

Answer 2

Answer:

p + q = 12 and pq = 22.

Using algebraic property:

(p+q)^2=p2+2pq+q2

(12)^2=p2+2×22+q2

144=p2+44+q2

144-44=p2+q2

100=p2+q2

therefore p2+q2=100
