Given the expression 5x² - 6x - 8, we have:
a = 5
b = -6
c = -8

We need to find two numbers m and n such that their product is ac (5 * -8 = -40) and their sum is b (-6).

The numbers that satisfy these conditions are -10 and 4:

m = -10
n = 4

Now, let's rewrite the middle term (-6x) using these values:
-6x = -10x + 4x

Now w...
