Question

Evaluate using suitable identities (1/2 p - 1/3 q)^2

Answer 1

Answer:

1/4P²-1/3pq+1/3q² is the answer

Answer 2

Answer:

1/4 p^2 - 1/3 pq + 1/9 q^2

Step-by-step explanation:

Using 2nd identity

(a-b)^2 = a^2 - 2ab + b^2

(1/2 p - 1/3 q)^2=(1/2 p)^2 - (2×1/2p×1/3q) +(1/3 q)^2

=1/4 p^2 - 1/3 pq + 1/9 q^2
