Question

Calcule (x²-3x-6).(5x-2) ​

Answer 1

Resposta:

(x²-3x-6).(5x-2) ​

5x³-2x²-15x²+6x-30x+12

5x³-17x²-24x+12

Answer 2

Resposta:

Explicação passo a passo:

Calcule (x²-3x-6).(5x-2) ​

= 5x.x^2 - 2.x^2 - 3x.5x - 3x.(-2) - 6.5x -6.(-2)

= 5x^3 - 2x^2 - 15x^2 + 6x - 30x + 12

= 5x^3 - 17x^2 - 24x + 12
