Question

Calcula el cubo de un binomio en cada caso
A. (a + 2)^3
B. (a - 4)^3
C. (m - 2/7)^3
D. (m + 5/4)^3
E. (2/3 + x)^3
F. (n - 2/7)^3

Answer 1

(a+2)^3= a^3+6a^2+12a+8
(a-4)^3= a^3-12a^2+48a-64
(m-2/7)^3= 343m^3-294m^2+84m-8/343
(m+5/4)^3= 64m^3+240m^2+300m+125/64
(2/3+x)^3= 27x^3+54x^2+36x+8/27
(n-2/7)^3= 343n^3-294n^2+84n-8/343

Answer 2

Respuesta:

A.(a+2)^3= a^3+6a^2+12a+8

B.(a-4)^3= a^3-12a^2+48a-64

C.(m-2/7)^3= 343m^3-294m^2+84m-8/343

D.(m+5/4)^3= 64m^3+240m^2+300m+125/64

E.(2/3+x)^3= 27x^3+54x^2+36x+8/27

F.(n-2/7)^3= 343n^3-294n^2+84n-8/343
