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

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

(m + 5) (m - 3)

Your steps using foil should look like:

m * m m * - 3 5 * m 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
