Question

3ab(2a+4b)= 

(2x+y) 3x²=

-y (y²-2y)=

3(2x³-x²+2x+1)=

-2x(x²-3x+2)=

(a²+2ab+b²)x3a²=

​

Answer 1

Explicação passo-a-passo:

3ab.(2a + 4b) = 6a²b + 12ab²

(2x + y).3x² = 6x³ + 3x²y

-y.(y² - 2y) = -y³ + 2y²

3.(2x³ - x² + 2x + 1) = 6x³ - 3x² + 6x + 3

-2x.(x² - 3x + 2) = -2x³ + 6x² - 4x

(a² + 2ab + b²).3a² = 3a⁴ + 6a³b + 3a²b²
