Final answer:
The expression (5m – 3)(m + 2) is multiplied using the FOIL method, resulting in 5m^2 + 10m – 3m – 6. After combining like terms, the simplified expression is 5m^2 + 7m – 6.
Step-by-step explanation:
To multiply and collect like terms for the expression (5m – 3)(m + 2), we use the distributive property (also known as the FOIL method). We multiply each term in the first parenthesis by each term in the second parenthesis.
Here are the steps:
- Multiply the first terms: 5m × m = 5m2.
- Multiply the outer terms: 5m × 2 = 10m.
- Multiply the inner terms: –3 × m = –3m.
- Multiply the last terms: –3 × 2 = –6.
Next, we combine the like terms:
- 5m2 (from step 1)
- 10m – 3m = 7m (from step 2 and 3 combined)
- –6 (from step 4)
Therefore, the fully simplified expression is 5m2 + 7m – 6.
