Question

The area of a rectangle is 2x2 - 11x + 15 square feet. the length of the rectangle is 2x - 5 feet. what is the width of the rectangle?

Answer 1

the area is = the length*the width
2x^2-11x+15= (2x-5)* the width
you have to divide 2x^2 - 11 x + 15 at 2x-5
 2x^2-11x+15   |  2x-5
-2x*2+5x                 x-3
-------------
/       -6x+15
        +6x-15
-----------------
          /   /
the answer is X-3
