Product means multiplication. Multiply via distribution. Just remember this rule:
a(b+c)=ab+bc
a(b-c)=ab-bc
So applying this, you get: 10x-4

Product for question as given:-
10x - 4
Product for (5 x - 2)² (just in case!):-
(5x - 2)(5x - 2)
25x² - 20x + 4

but if you mean (5x-2)^2 or (5x-2) squared then,
(5x-2)^2
=25x^2 - 10x + 4

= 2(5x - 4)
= 10x - 8
Answer: 10x - 8

well...
(ax - b)^2 = ax^2 - 2ab + b^2
so you get:
25x^2 - 20x + 4
