Certainly! Let's simplify the given expressions step by step:
Factor out the common term 'a' from both terms:
a(b - 4)
So, the simplified expression is: a(b - 4)
Factor out the common term 'b' from both terms:
b(4 - a)
So, the simplified expression is: b(4 - a)
Factor out the common term '4' from both terms:
4(a - b)
So, the simplified expression is: 4(a - b)
Putting it all together, the simplified expressions are:
