Question

p-q=8, pq=6 then (p+q x p+q)

Answer 1

Answer:

86

Step-by-step explanation:

Apply the formula of (a-b)^2

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

p^2+q^2=8^2+2(6)

p^2+q^2=64+12

p^2+q^2=76

now apply a+b ka square

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

putting values

76+12

86

here (p+q)×(p+q)=(p+q)^2

HENCE (p+q)^2=86
