Question 100121
Your first step is to look at the equation for the area of a rectangle which is
Area=length times width
So your problem would look like this...
x^3-6^2+15x-24= x-4 times l (l=to length)
you want to end up with just l on one side, so you get rid of the x by subracting from both sides, which would look like this...
x^3-6^2+14x-24 notice that 15 x changed to 14 x because you subtracted an x.
now to get rid of the 4 you divide on both sides, and it will look like this...
x^3/4-6x^2/4+14x/4-24/4 if you simplify youŽd end up with 
x^3/4-3x^2/2+7x/2+6 and that would be your answer.
