Given the expression 7x² - 18x + 8, we have:
a = 7
b = -18
c = 8

We need to find two numbers m and n such that their product is ac (7 * 8 = 56) and their sum is b (-18).

The numbers that satisfy these conditions are -4 and -14:

m = -4
n = -14

Now, let's rewrite the middle term (-18x) using these values:
-18x = -4x - 14x

Now...
