Question

How do you use the distributive property to factor `21b-15a`?

Answer 1

See the solution process below:

Explanation:

First, factor a `color(red)(3)` from each term and rewrite the expression as:

`(color(red)(3) * 7b) - (color(red)(3) * 5a)`

Now, factor the `color(red)(3)` out of both terms:

`color(red)(3)(7b - 5a)`
