Binomios

Binomio al cuadrado:
(3a-2b)2= 9a2-12ab+4b2
(-2x2-6y2)= 4x4+24x4y2+36y4
(3p-cd)2= 9p2+ 42pq+49q2
(3ab-cd)2= 9a2b2- 6abcd+c2d2
(4/3a-2/5x)2= 16/9a2-16/15ax+4/25x2

Binomio al cubo:
(a-b)3= a3- 3a2b-3ab2- b3
(3xy-4ab)3= 27x3y3-108x2y2ab+144xya2b2- 64a3b3
(x2- ay)3= x6-3x4ay+3x2a2y2- a3y3
(2y2-6w)3= 8y6-72y4w+216y2w2-216y 3w3
(-2x2+ 3a)3= -8x6+36ax4-54a2x2+27a3
