Expanding the Expression (2x + 5)(4x - 7)
This article will guide you through the process of expanding the expression (2x + 5)(4x - 7). We will use the FOIL method, which stands for First, Outer, Inner, Last.
Applying FOIL
- First: Multiply the first terms of each binomial: (2x)(4x) = 8x²
- Outer: Multiply the outer terms of the binomials: (2x)(-7) = -14x
- Inner: Multiply the inner terms of the binomials: (5)(4x) = 20x
- Last: Multiply the last terms of the binomials: (5)(-7) = -35
Combining Like Terms
Now, we have: 8x² - 14x + 20x - 35
Combine the x terms: 8x² + 6x - 35
Final Result
Therefore, the expanded form of (2x + 5)(4x - 7) is 8x² + 6x - 35.
