Multiplying (x-5)(x+2)
This article will guide you through multiplying the expression (x-5)(x+2).
Understanding the Process
The expression (x-5)(x+2) represents the product of two binomials. To multiply binomials, we use the distributive property, often referred to as 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 FOIL
- First: (x) * (x) = x²
- Outer: (x) * (2) = 2x
- Inner: (-5) * (x) = -5x
- Last: (-5) * (2) = -10
Combining Like Terms
Now we have: x² + 2x - 5x - 10
Combine the like terms (2x and -5x):
x² - 3x - 10
Final Result
Therefore, the product of (x-5)(x+2) is x² - 3x - 10.
