Question

a) (x + y)²
b) (2a + b)²
c) (x – 4y)²
d) (6 - a³)²​

Answer 1

Explicação:

(x + y)²

x²+2xy+y²

(2a + b)²

(2a)²+2.2ab+b²

4a²+4ab+b²

(x – 4y)²

x²-2x.4y+(4y)²

x²-8xy+16y²

(6 - a³)²

36-12a³+a⁶

a⁶-12a³+36

Answer 2

Resposta:

a) (x+y)²

(x+y)(x+y)

x²+xy+xy+y²

x²+2xy+y²

b) (2a+b)²

(2a+b)(2a+b)

4a²+2ab+2ab+b²

4a²+4ab+b²

c) (x-4y)²

(x-4y)(x-4y)

x²-4xy-4xy-16y²

x²-8xy-16y²

d) (6-a³)²

(6-a³)(6-a³)

36-6a³-6a³-a⁶

36-12a³-a⁶
