Sure, let's factorise the expression step by step:

1. First, we can group the terms to make it easier to factorise: (7r^2 + 7rs) - (4r + 4s)

2. Then, we can factor out the common factors in each group: 7r(r + s) - 4(r + s)

3. Now, you can see that (r + s) is a common factor in both terms, so we can factor that out: (7r - 4)(r + s)

So, the expression 7r^2 + 7rs - 4r - 4s factorises to (7r - 4)(r + s).
