Question

How do you simplify `4(8p+4q-7r)`?

Answer 1

`32p + 16q - 28r`

Explanation:

To simplify this you must multiply `4` by each term in the parenthesis:

`color(blue)(4)(color(red)(8p + 4q - 7r)) ->`

`(color(blue)(4) * color(red)(8p)) + (color(blue)(4) * color(red)(4q)) - (color(blue)(4) * color(red)(7r))`

`32p + 16q - 28r`
