Expanding and Simplifying the Expression (3m+1)(m+9)
The expression (3m+1)(m+9) is a product of two binomials. To simplify it, we can use the FOIL method, which stands for First, Outer, Inner, Last.
Here's how to apply FOIL:
- First: Multiply the first terms of each binomial: (3m) * (m) = 3m²
- Outer: Multiply the outer terms of each binomial: (3m) * (9) = 27m
- Inner: Multiply the inner terms of each binomial: (1) * (m) = m
- Last: Multiply the last terms of each binomial: (1) * (9) = 9
Now, we have the simplified expression: 3m² + 27m + m + 9
Finally, combine the like terms: 3m² + 28m + 9
Therefore, the expanded and simplified form of (3m+1)(m+9) is 3m² + 28m + 9.
Note: This expression represents a quadratic equation. It can be used to solve for the values of m that make the equation equal to zero.
