Объяснение:

7x² - y²a + 7x²a - ya²=7х²(1-а)-уа(у+а)

Answer 2

It seems like you have provided an expression with variables x and y, as well as the variable 'a'. To simplify this expression, let's group like terms together:

7x^2 - y^2a + 7x^2a - ya^2

Now, let's factor out common terms:

7x^2 + 7x^2a - y^2a - ya^2

Notice that the first two terms have a common factor of 7x^2, and the last two terms have a common factor of -ya^2:

7x^2(1 + a) - ya^2(1 + a)

Now, you can factor out the common factor of (1 + a):

(7x^2 - ya^2)(1 + a)

So, the simplified expression is:

(7x^2 - ya^2)(1 + a)
