Homework Help: Pre-Calc

Posted by Andy G on Tuesday, January 14, 2014 at 6:29pm.

An open box with a volume of 1500cm^3 is to be constructed by taking a piece of cardboard of 20 cm by 40 cm, cutting squares of sides length x cm from each corner and folding up the sides. Show that this can be done in two different ways, and find exact dimensions of the box in each case.

I have already found the solution using the quadratic equation, can someone help me find the solution using synthetic division?
