p2-q2p+q÷p+qp-q
Since both terms are perfect squares, factor using the difference of squares formula, a2-b2=(a+b)(a-b) where a=p and b=q.
(p+q)(p-q)p+qp+qp-q
Reduce the expression (p+q)(p-q)p+q by cancelling the common factors.
Cancel the common factor.
(p+q)(p-q)p+qp+qp-q
Rewrite the expression.
p-q1p+qp-q
p-q1p+qp-q
Divide p-q by 1.
p-qp+qp-q
p-qp+qp-q
Factor ((p^2-q^2)/(p+q))÷((p+q)/(p-q))
