ПОМОГИИЕ ПОЖАЛУЙСТА С АЛГЕБРОЙ​

Answer 1

$\displaystyle\bf\\\frac{a^{2} -2ab+b^{2} }{a^{2} -b^{2} }+\frac{ab}{a^{2} +2ab+b^{2} } =\frac{(a-b)^{2} }{(a-b)(a+b)} +\frac{ab}{(a+b)^{2} } =\\\\\\=\frac{a-b}{a+b} +\frac{ab}{(a+b)^{2} } =\frac{(a-b)\cdot(a+b)+ab}{(a+b)^{2} } =\frac{a^{2} -b^{2} +ab}{(a+b)^{2} } \\\\\\a=2 \ \ ; \ \ b=3\\\\\\\frac{a^{2} -b^{2} +ab}{(a+b)^{2} } =\frac{2^{2} -3^{2} +2\cdot 3}{(2+3)^{2} } =\frac{4-9+6}{5^{2} } =\frac{1}{25} =0,04\\\\\\Otvet \ : \ 0,04$
