"The length of a rectangle is twice the width. the area is 50 yd^2" -----> LW=50
and L=2W
--->
(2W)W=50
2W^2=50
W^2=25
W=5...
L=2*5=10
Ans: width: 5, length: 10

" A student opens a mathematics book to two facing pages" ----> x(x+1)=2162
x^2+x=2162
x^2+x-2162=0
(x-46)(x+47)=0
x=46, x=-47
Ans: pages are 46 and 47
