Question 300088: What is the product of (x+3)(x+4}?
Answer by mathfolife(2)   (Show Source):
You can put this solution on YOUR website! The formula for multiplying those together is....
(x+a)(x+b)= x^2+ ax+bx+ ab= x^2+(a+b)x+ab
You can also use the acryonm FOIL to help compute the problem. FOIL= First Outer Inner Last
What you do is first multiple the first term in each polynomial together
x * x
then you multiple the outer terms
x*b
then the inner
a*x
and finally the last
a*b
you add them all up and get x^2+ax+bx+ab
heres an example....
(x+2)(x+5)
First = x^2
Outer= 5x
Inner =2x
Last = 10
ANSWER: x^2+5x+2x+10
