Question

Cократите дробь:

      числитель:9p^2-q^2

знаменатель:9p:2+6pq+q^2

Answer 1

(3p-q)(3p+q)     (3p-q)

 

-------------=---------

 

(3p+q)^2          (3p+q)

Answer 2

$frac{9p^{2}-q^{2}}{9p^{2}+6pq+q^{2}}=frac{(3p-q)(3p+q)}{(3p+q)^{2}}=frac{(3p-q)(3p+q)}{(3p+q)(3p+q)}=frac{3p-q}{3p+q}$
