Polynomials FOIL

FOIL or NOT FOIL?

(5x-11)(x+1)

• FOIL - this is multiplication of two binomials

• NOT FOIL - this is the addition of two binomials, so combine like terms

• NOT FOIL - need to distribute the negative and then combine like terms

FOIL or NOT FOIL?

5(x-1) - (4x+9)

• FOIL - this is multiplication of two binomials, so distribute 5 then FOIL

• NOT FOIL - this is the addition of two binomials, so combine like terms immediately

• NOT FOIL - need to distribute the 5 and the negative and then combine like terms
