Question 1156399: If the length of a rectangle is 7 meters less than twice the width, we have
L=2W-7
If the area is 60 square meters, we have
L×W=60 substitute L
(2W-7)×W=60
2W^2-7W=60
2W^2-7W-60=0
2W^2-15W+8W-60=0
(2W^2+8W)-(15W-60)=0
2W(W+4)-15(W+4)=0
(W+4)(2W-15)=0
2W-15=0 W=15/2 W=7.5
Can someone explain where the 15 and 8 came from?
