What is the FOIL method?
Answer
The FOIL(First, Outer, Inner, Last) method is where you are multiplying two binomials. Which is then simplified by simply combining like terms.
Lets do an example and break down the steps.
(x+2)(x+3)
1st First = (x)(x)=X^2
2nd Outer= (x)(3)=3x
3rd Inner=(2)(x)=2x
4th Last= (2)(3)=6
So we have x^2+2x+3x+6 now our next step would be to combine like terms. We have 2x and 3x which gives us 5x.
Now our answer is x^2+5x+6
