Multiply away! What's stopping you?

Sorry posted the wrong question

OpenStudy (anonymous):

I meant to post this question (2x+1)(3+x)

OpenStudy (trojanpoem):

It's the same. maybe the previous was harder xD

OpenStudy (trojanpoem):

2x * 3 + 2x * x + 1 * 3 + 1 *x ( self-explaining)

OpenStudy (tkhunny):

In that case, Multiply away! What's stopping you?

OpenStudy (anonymous):

I was just wondering if I used FOIL to solve the problem

OpenStudy (tkhunny):

FOIL doesn't exist. Just learn to multiply. Do you use FOIL to multiply 23 * 57? No. You just multiply each piece until you get them all. You cannot use FOIL in (x^2 + x + 4)(X - 4) Seriously, forget you ever heard of FOIL.
