$-3m^2np+5mn^2p-35mnp^2$

$1$ . Recall the distributive property: $a(b+c)=ab+ac$ . Thus, in your equation, multiply $color(red)(-mnp)$ by each term inside the brackets.

$color(red)(-mnp)(3m-5n+7p)$

$=color(red)(-(mnp))(3m)color(red)(-(mnp))(-5n)color(red)(-(mnp))(7p)$

$2$ . Simplify.

$=-3m^2np+5mn^2p-35mnp^2$

How do you multiply -mnp(3m - 5n + 7p)-mnp(3m - 5n + 7p)?
