What to Do How to Do It
1. Look again at the product of two binomials, and see how we use the method called the double distributive property.   → (A + B)(C + D)

  = A(C + D) + B(C + D)

  = AC + AD + BC + BD

2. Generally, product of two linear binomials is multiplied by the method called F O Ι L.

to obtain a quadratic (2nd degree) trinomial:

F = the product of the first terms:

O = the product of the outer terms:

Ι = the product of the inner terms

L = the product of the last terms

Algebraically add the O + Ι = adx + bcx = Bx.

  (ax + b)(cx + d)

  → Ax2 + Bx + C

  Ax2 = ax·cx = acx2

  C = b·d = bd

  acx2 + (ad +bc)x + bd .

  = Ax2 + Bx + C

3. For general linear (first degree) binomials with common terms:

The double distributive property is used vertically - the “outer” and “inner” are placed directly below and then added algebraically along with the product of the “firsts” and “lasts”.

The algebraic sum is the Product:

  → (ax + b)(cx + d)
