#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!
