Question

(2x elevado a 2 - 3x - 6) • (5x - 2)

Answer 1

$(2 x^{2} - 3x -6) . (5x - 2)$
$10x^{3} -4x^{2} - 15x^{2} + 6x - 30x + 12 10x^{3} - 19x^{2} - 24x + 12$

Answer 2

= (2x² - 3x - 6).(5x - 2)
= 2x².5x + 2x².(-2) - 3x.5x - 3x.(-2) - 6.5x - 6.(-2)
= 10x³ - 4x² - 15x² + 6x - 30x + 12
= 10x³ - 19x² - 24x + 12
