Question

(а/а-в) + (а^2+в^2/ в^2-а^2) + (а/а+в) какой ответ ?

Answer 1

$\frac{a}{a-b} + \frac{ a^{2} + b^{2} }{ a^{2} - b^{2} } + \frac{a}{a+b}$
Так как $a^{2} - b^{2} = (a-b)*(a+b)$ , то приводим к общему знаменателю:
$\frac{a(a+b)+ a^{2}+ b^{2} + a(a-b) }{(a-b)(a+b)}$
Раскрываем скобки:
$\frac{ a^{2}+ab+ a^{2}+ b^{2} + a^{2}-ab }{(a-b)(a+b)} = \frac{ a^{6} + b^{2} }{(a-b)(a+b)}$ 

Answer 2

Solution

To solve the given expression (a^2 + b^2) / (b^2 - a^2) + (a / (a + b)), we can follow these steps:

1. Factorize the numerator and denominator: Factorizing the numerator and denominator will help simplify the expression.

2. Simplify the expression: After factorizing,
