Question

A)  x(a+b)+y(a+b)=б)  (a+b)a-b(a+b)=

Answer 1

А) (a+b)(x+y)
б)  $(a+b)(a-b) = a^{2} - b^{2}$

Answer 2

It looks like you have two equations, A and B, and you'd like to solve them. Let's work through them one at a time.

A) x(a+b) + y(a+b)

We can see that both terms in equation A have a common factor of (a + b). We can factor it out:

x(a + b) + y(a + b) = (a + b)(x + y)

So, equation A simplifies to:

(a + b)(x + y)

B) (a + b)a - b(a + b)

Again, we can see that both terms in equation B have a common factor of (a + b). We can factor it out:

(a + b)a - b(a + b) = (a + b)(a - b)

So, equation B simplifies to:

(a + b)(a - b)

Now you have both equations simplified:

A) (a + b)(x + y) B) (a + b)(a - b)

If you have specific values for x, y, a, and b, you can further simplify or solve for specific solutions. If you need to solve for any variables, please provide more information, and I'll be happy to assist you further.
