The area of a rectangle is 2x^2+5x^2x6 cm. write a polynomial that represents its width if its length is 2x^2+ x3.

You must have meant:
area is 2x^3+5x^2x6
if so, then it factors nicely into
(x1)(x+2)(2x+3)
and the width of 2x^2 + x  3 factors to (2x+3)(x1)
then
(2x^3+5x^2x6) รท (2x^2+ x3)
= (x1)(x+2)(2x+3)/( (2x+3)(x1) )
= x+2
or
you could do a long algebraic division as it stands and also get x+2 
thanks a lot!
