(4x – 4)(5x + 2)
Find each product

To multiply these two binomials, we will use the F.O.I.L. method.

First-Outer-Inner-Last

First take the product of the first terms, which is 20x².

Then take the product of the outer terms which is 8x.

Then the product of the inner terms which is -20x.

Lastly take the product of the last terms which is -8.

Now let's combine like terms.

So our final answer is 20x^2 - 12x - 8.

6mm^3 or .6cm^3
