So you gotta use the AC method. What two numbers multiply to 4 and add to negative 5? It’s -4 and -1. Now you split up the -5 and then factor
I will show you how. 4x^2 -4x -1x +1
Now factor that —> 4x(x-1) -1 (x-1) see how there are two (x-1)?
We simplify it to (x-1)(4x-1) I took the two numbers of the outside and put them together. Now see that you multiply it out you get ur original unfactkred equation
D is the answer

Energy is created by the movement of electric charges called electrons among the atoms of matter.
P=18
l=5 cm greater than the width
w=5 less than the length
USE YOUR NUMBER SENSE!!! - just plug in different number below 4 to figure out the width
3=w 3+5=8 8+8=16+6=22 WILL NOT WORK
2=w 2+5=7 7+7=14 14+2+2= 18 WE HAVE A WINNER!!!!
