Given the expression 7a² + 53a + 28, we have:
a = 7
b = 53
c = 28

We need to find two numbers m and n such that their product is ac (7 * 28 = 196) and their sum is b (53).

The numbers that satisfy these conditions are 4 and 49:

m = 4
n = 49

Now, let's rewrite the middle term (53a) using these values:
53a = 4a + 49a

Now we ...
