Answer: (1-y)(a-7) and (8a-1)(x+y)

Explanation:

When the values in the parentheses are the same twice, they reappear only once after grouping. In the first problem, the coefficients are 1 and -y, therefore, the answer becomes (1-y)(a-7).


Hope this helps

Answer:

(x+y)(8a - 1)

Explanation:

For the first expression:

(a-7) - y(a-7)

We can factor out (a-7) from both terms:

(a-7)(1 - y)

So, the factored expression is:

(a-7)(1 - y)

For the second expression:

8a(x+y) - (x+y)

We can factor out (x+y) from both terms:

(x+y)(8a - 1)

So, the factored expression is:

(x+y)(8a - 1)
