Shihok $\frac{a^2+2ab+b^2}{a^2+ab+b^2}* \frac{a^3-b^3}{7a+7b}= \frac{(a+b)^2}{a^2+ab+b^2}* \frac{(a-b)(a^2+ab+b^2)}{7(a+b)}= \frac{(a+b)(a-b)}{7}= \frac{a^2-b^2}{7} \\ \\ \frac{m^2+2mn+n^2}{p^3+c^3}* \frac{p+c}{2m+2n}=\frac{(m+n)^2}{(p+c)(p^2-pc+c^2)}* \frac{p+c}{2(m+n)}= \frac{m+n}{2(p^2-pc+c^2)}$

1) (а+в)^2 / а^2+ab+b^2 * a^3-b^3 / 7(a+b)= (a+b)^2 / a^2+ab+b^2 * (a-b)(a^2+ab+b^2) / 7(a+b) = (a+b)(a-b) /7= a^2-b^2 /7
2) (m+n)^2 / (p+c)(p^2-pc+c^2) * p+c / 2(m+n)= m+n/ 2(p^2-pc+c^2)
