Question

3 — Complete os espaços:

a)(___+3)² = a² +6a+____

b)(2a+____)³ = 8a³+____+54ab²+ 27b³

c)(3a²- 2b)² = _______ -12a2b+ _____​

Answer 1

Resposta:

a) (___+3)² = a²+6a+___

( a + 3)² = a²+6a+9 )

b) (2a+___)³ = 8a³+___+54ab²+27b³

(2a+ 3b)³ = 8a³+36a²b+54ab²+27b³

c) (3a²-2b)² = ___-12a²b+___

(3a²-2b)² = 9a⁴-12a²b+ 4b²

Answer 2

Resposta:

A) ( a +3)2 = a2 + 6a + 9

B) (2a + 3b)3 = 8a3 + 36a²b + 54 ab2 + 27b3

C) (3a2 - 2b)2 = 9a⁴ - 12 a2b + 4b²
