Answer:
–16(x2 – 3x – 4)
first we have to distribuite
-16x^2+48x+64
then we have to look for a number that goes into all of these which is -16
x^2-3x-4
then multiply the first by the last
-4x^2
then we have to find a two number that adds to make -3 and multiples to make -4x2
now lets list the factors
2*2
4*1
then lets just plug in
(x^2+x)(-4x-4)
now we have to factor out
x(x+1)-4(x+1)
-16(x-4)(x+1)
Hope This Helps!!!
