Expanding the Expression: (1-4m)(m^2-3m+8)
This expression involves multiplying two binomials. We can use the distributive property (also known as FOIL) to expand it.
FOIL stands for:
- First: Multiply the first terms of each binomial.
- Outer: Multiply the outer terms of each binomial.
- Inner: Multiply the inner terms of each binomial.
- Last: Multiply the last terms of each binomial.
Let's apply this to our expression:
(1-4m)(m^2-3m+8)
1. First: 1 * m^2 = m^2
2. Outer: 1 * -3m = -3m
3. Inner: -4m * m^2 = -4m^3
4. Last: -4m * -3m = 12m^2
5. Last: -4m * 8 = -32m
Now, we combine the terms:
m^2 - 3m - 4m^3 + 12m^2 - 32m
Finally, we rearrange the terms in descending order of their exponents:
-4m^3 + 13m^2 - 35m
Therefore, the expanded form of (1-4m)(m^2-3m+8) is -4m^3 + 13m^2 - 35m.
