I need some help with simplifying some quadratic equations. They are all word problems. Here is one. Please Help!!!
The length of a photograph is 1cm less than twice the width. The area is 45squarecm. Find the dimensions of the photograph.
This is what I have so far:
w=width
w (2w-1) = 45
2w^2 - w = 45
2w^2 - w - 45 = 0
Now what????
Thanks
