(b+2)(b2-2b+4)
(5+z)3
(c+3).(3-c)3
ayudenme xfa

Answer 1

(5+b)(25-5a+a²)= 125-25a + 5a²+25b-5ab+5a²

(x-3)(x²+3x+9)
= xx²+3x²+9x-3x²-9x-27
=x³-27

(b+2)(b²-2b+4)
=b³-2b²+4b+2b²-4b+8
=b³+8

(5+z)³
= 5³+3(5)²(z)+3(5)(z)²+z³
=125+75z+15z²+z³

(c+3)(3-c)³

1)Resolveremos la diferencia del Cubo
(3-c)³
= 3³-3(3)²(c)+3(3)(c)²+c³
=27-27c+9c²+c³

2)Resolvemos la operación

(c+3)(27-27c+9c²+c³)
=27c-27c²+9c³+c⁴+81-81c+27c²+3c³
=-54c+12c³+c⁴+81
