Multiply: $(4 + x)(x^2 + 2x +3)$ How would I solve this:
Multiply:  $(4 + x)(x^2 + 2x +3)$

First, distribute the 4. Add the products of 4 and $x^2$, 4 and 2x, 3 and 4. 
Then, distribute the x. Add the products of x and $x^2$, x and 2x, 3 and x. 
Then all you have to do is add all of the items you have left. 
After the distributions, you should have 
$4x^2 + 8x + 12 + x^3 + x^2 + 3x =$
$x^3 + 5x^2  +11x + 12$
(Yay cool text!)
