Expanding the Expression (2m + 1)(4m - 4)
This expression represents the product of two binomials, (2m + 1) and (4m - 4). To simplify it, we can use the FOIL method, which stands for First, Outer, Inner, Last.
Here's how it works:
- First: Multiply the first terms of each binomial: (2m) * (4m) = 8m²
- Outer: Multiply the outer terms of the binomials: (2m) * (-4) = -8m
- Inner: Multiply the inner terms of the binomials: (1) * (4m) = 4m
- Last: Multiply the last terms of each binomial: (1) * (-4) = -4
Now, we combine all the terms:
8m² - 8m + 4m - 4
Finally, we simplify by combining like terms:
8m² - 4m - 4
Therefore, the expanded form of (2m + 1)(4m - 4) is 8m² - 4m - 4.
