Simplifying the Expression (2x + 5)(3x + 4)
This article will guide you through simplifying the expression (2x + 5)(3x + 4).
Understanding the Process
The expression (2x + 5)(3x + 4) represents the product of two binomials. To simplify it, we will use the FOIL method:
- First: Multiply the first terms of each binomial.
- Outer: Multiply the outer terms of the binomials.
- Inner: Multiply the inner terms of the binomials.
- Last: Multiply the last terms of each binomial.
Applying the FOIL Method
- First: (2x) * (3x) = 6x²
- Outer: (2x) * (4) = 8x
- Inner: (5) * (3x) = 15x
- Last: (5) * (4) = 20
Combining Like Terms
Now, we have: 6x² + 8x + 15x + 20
Combining the 'x' terms, we get: 6x² + 23x + 20
Final Simplified Expression
Therefore, the simplified form of (2x + 5)(3x + 4) is 6x² + 23x + 20.
Conclusion
Simplifying algebraic expressions is a crucial skill in mathematics. Understanding the FOIL method and combining like terms allows us to manipulate expressions and obtain a more concise form.
