Place the indicated product in the proper location on the grid.

(5c + 2/3) (5c - 2/3)

Answer

25c^2-4/9

Explanation

In this question you are expected to expand (5c+2/3) (5c-2/3)

(5c+2/3) (5c-2/3) = (5c*5c) - (5c*2/3) + (5c*2/3) - (2/3*2/3)

=25c^2-10c/3+10c/3-4/9

25c^2-4/9

The expanded form of (5c+2/3) (5c-2/3) is 25c^2-4/9 and this is what the question requires of you to do.
