8x² - 32 x = 0
8x(x - 4) = 0
8x = 0 y x - 4 = 0
x = 0 x = 4
Entonces x toma 2 valores {0 , 4}
Segunda:
a³ - 125
a³ - 5³ = (a - 5)(a² +5a + 25)
Tercera:
1 + 343n³ = 1³ + 7³n³ = 1³ +(7n)³
1³ +(7n)³ = (1 + 7n)(1² + 7n + (7n)²)
= (1 + 7n)(1 + 7n + 49n²)
8x(x-4) = 0
8x = 0 x-4 = 0
x = 0/8 x = 4
x = 0 x= 4
CS = (0; 4)
factorizacion de un cubo
a^3 - 125
1 + 343n^3
