Question

(p-q) – (p+q) pls do it fast​

Answer 1

Answer:

(p+q)(p-q)

=> px(p-q) + qx(p-q); (using Distributive Law)

=> p^2 - pq + qp - q^2

=> p^2 - q^2 (pq is same as qp so both nullify each other)

So, the correct answer is (p+q)x(p-q) = p^2 - q^2.

Answer 2

Answer:

(p+q)(p-q)

=> px(p-q) + qx(p-q); (using Distributive Law)

=> p^2 - pq + qp - q^2

=> p^2 - q^2 (pq is same as qp so both nullify each other)

So, the correct answer is (p+q)x(p-q) = p^2 - q^2.
