Expanding the Expression: (2x-3)(5x+6)
This article will explore the process of expanding the expression (2x-3)(5x+6). This involves applying the distributive property, often referred to as FOIL (First, Outer, Inner, Last).
Expanding using FOIL
- First: Multiply the first terms of each binomial: 2x * 5x = 10x²
- Outer: Multiply the outer terms of the binomials: 2x * 6 = 12x
- Inner: Multiply the inner terms of the binomials: -3 * 5x = -15x
- Last: Multiply the last terms of each binomial: -3 * 6 = -18
Now we have: 10x² + 12x - 15x - 18
Simplifying the Expression
Combine the like terms: 10x² + (12x - 15x) - 18
The simplified expression is: 10x² - 3x - 18
Conclusion
Therefore, the expanded and simplified form of the expression (2x-3)(5x+6) is 10x² - 3x - 18. This process involves utilizing the distributive property and combining like terms for a concise result.
