Kaksliikme summa ruudu saame, kui korrutame kaksliikme iseendaga. Seejuures saame kasutada kasliikmete korrutamis reeglit.

Kaksliikme summa ruut

(a+b)² = (a+b)(a+b)=a²+ab+ab+b²=a²+2ab+b²

Näide:

Liugurite abil saab muuta a ja b pikkust.

a = 1 (slider from 1 to 8, step 1)
b = 5 (slider from 1 to 5, step 1)

B = Point(Circle[A, c])
f = Segment(A, B)
hulknurk1, g, h, i, j, C, D = Polygon(A, B, 4)
E = Point(Circle[A, a])
k = Segment(A, E)
hulknurk2, l, m, n, p, F, G = Polygon(A, E, 4)
