Binomial Expander

Explore the Area Model

Adjust the sliders to see how $(a+b)(c+d)$ breaks into four partial products.

a 2

b 3

c 4

d 1

(2 + 3)(4 + 1) = 8 + 2 + 12 + 3 = 25

ac = 8

ad = 2

bc = 12

bd = 3

First (ac) Outer (ad) Inner (bc) Last (bd)

Expand each binomial product. Type your answer in simplest form with terms ordered by power (e.g. x^2+5x+6).

Expand (x + 2)(x + 3)
