Multiplying (2x+4)(x-4)
This article will guide you through the steps of multiplying the expression (2x+4)(x-4). We will use the FOIL method, which stands for First, Outer, Inner, Last.
FOIL Method
- First: Multiply the first terms of each binomial: (2x) * (x) = 2x²
- Outer: Multiply the outer terms of each binomial: (2x) * (-4) = -8x
- Inner: Multiply the inner terms of each binomial: (4) * (x) = 4x
- Last: Multiply the last terms of each binomial: (4) * (-4) = -16
Combining Like Terms
Now we have: 2x² - 8x + 4x - 16
Combine the like terms: 2x² - 4x - 16
Final Result
Therefore, the product of (2x+4)(x-4) is 2x² - 4x - 16.
