Question

Write an equivalent expression for (m+5)(m-3)

Answer 1

Solve using the foil method (first, outside, inside, last).

(m + 5)(m - 3)

Your steps using foil should look like:

1. m * m
2. m * -3
3. 5 * m
4. 5 * -3

After multiplying, rewrite your expression.

m² - 3m + 5m - 15

The last step to simplifying this expression is to combine like terms, which are -3m + 5m.

m² + 2m - 15
