$x^2-28x+16$

Multiply the $3x$ and the -4 by $4x$ , then multiply the $3x$ and the-4 by -4.

$=>$ $12x^2-16x-12x+16$

Collect like terms

$x^2-28x+16$

$12x^2 - 28x - 16$

To solve this, we use the distributive property.

$4x * 3x - 4 * 3x + 4x * -4 + -4 * -4$

Combine and simplify:
$12x^2 - 12x - 16x + 16$

Combine like terms ( $-12x$ and $-16x$ )
$12x^2 - 28x + 16$

Hope this helps!
