Efetue: a) (x - 1)3 b) (x + 2)3 c) (2x - 1)3 d) (2x + 5)3 e) (3x - 2)3 f) ( x2 - 3m) 3

Answer 1

Boa tarde

a)

(x - 1)^3 = x^3 - 3x^2 + 3x - 1

b)

(x + 2)^3 = x^3 + 6x^2 + 12x + 8

c)

(2x - 1)^3 = 8x^3 - 12x^2 + 6x - 1

d)

(2x + 5)^3 = 8x^3 + 60x^2 + 150x + 125

e)

(3x - 2)^3 = 27x^3 - 54x^2 + 36x - 8

f) (x^2 - 3m)^3 = -27m^3 + 27m^2x^2 - 9mx^4 + x^6
