Something I’ve learned this week was multiplying polynomials using the FOIL technique. FOIL is a type of distributive property.
FOIL stands for – i,e (a+b)(c+d)
First term in each bracket (ac)
Outside terms (ad)
Inside terms (bc)
Last term in each bracket (bd)
For example:
(x + 6)(x + 4)
= + 4x + 6x + 24
Once you solved the multiplication after foiling, you the collect “like terms’
(x + 6)(x + 4)
= + 4x + 6x + 24
= + 10x + 24
Down below I included a picture that has arrows connecting the terms you multiply together.
I didn’t have any challenges with this chapter yet because it is mainly the same things that I did last year during polynomials in Math 9.
