Question

(x+4)(x+2)

Answer 1

FOIL. Ever heard of it?

Answer 2

Can you help me with this problem

Answer 3

Here's another way to think of the problem.
\[(x + 4)(x + 2) \rightarrow x(x + 2) + 4(x + 2) \rightarrow?\]

Answer 4

Yep, I have to teach you about FOIL first. It stands for FIRST INSIDE OUTSIDE LAST.

It means that you multiply those numbers and variables in the FOIL order.

that means x*x for F or First

x*x = x

O is outside, which is x and 2. x*2= 2x

so far we have x+2x.

Next comes I or inside, which is 4 and x.

x*4=4x.

and L is last, 4*2=8

So it looks something like this when you put it all together:

x+2x+4x+8. Make sense?

Answer 5

\[=x^2+8x+4x+32\]\[=x^2+12x+32\]
