Im assuming its x^2+4x+3.....for x squared right.
First get the product of two numbers that equal to 3 (+3 * +1)
But also add up to 4 (+3 + <span>+1</span>)
so you apply them to your x^2
(x+3)(x+1)
Approximately about $18,490
<span>PV= $15,000 </span>
<span>FV= solve for </span>
<span>PMT= 0 </span>
<span>I/YR= 7% </span>
<span>N= 36 </span>
<span>put these in your HP II calcu and you will get the approximate answer.

Factor out common factors.
-x³-4x²-5x = -x(x² + 4x + 5)
-x(x² + 4x + 5) is your answer
hope this helps
Parameterize the surface (call it
) by
with
and
. Then the surface element is
The area of
is then given by the surface integral
