Factoring and Expanding (v-5)(v+3)(v+2)
This expression involves multiplying three binomials: (v-5), (v+3), and (v+2). We can solve this by following these steps:
Step 1: Multiply the first two binomials.
We can use the FOIL method to multiply (v-5) and (v+3):
- First: v * v = v²
- Outer: v * 3 = 3v
- Inner: -5 * v = -5v
- Last: -5 * 3 = -15
Combining the terms, we get: v² + 3v - 5v - 15 = v² - 2v - 15
Step 2: Multiply the result from step 1 with the remaining binomial.
Now we have to multiply (v² - 2v - 15) with (v+2). We can use the distributive property:
- v² * (v + 2) = v³ + 2v²
- -2v * (v + 2) = -2v² - 4v
- -15 * (v + 2) = -15v - 30
Adding all the terms together: v³ + 2v² - 2v² - 4v - 15v - 30 = v³ - 19v - 30
Conclusion
Therefore, the expanded form of (v-5)(v+3)(v+2) is v³ - 19v - 30.
