Question

How do you simplify `(6m+1)(2m-5)`?

Answer 1

To simplify cross multiply each term in the left parenthesis by each term in the right parenthesis. See full process below:

Explanation:

`(color(red)(6m + 1))(color(blue)(2m - 5)) ->`

`(color(red)(6m) xx color(blue)(2m)) - (color(red)(6m) xx color(blue)(5)) + (color(red)(1) xx color(blue)(2m)) - (color(red)(1) xx color(blue)(5))`

`12m^2 - 30m + 2m - 5`

Now we can combine like terms:

`12m^2 + (-30 + 2)m - 5`

`12m^2 - 28m - 5`
