Answer:

[tex]2x^{3} + 3x^{2} - 11x - 6[/tex]

Step-by-step explanation:

(2x + 1)(x - 2)(x + 3)

Since there is multiplication i between all of these, I will multiply the first 2, then multiply it with the last one:

(2x + 1) (x - 2) = [tex]2x^{2} -3x - 2[/tex]

([tex]2x^{2} -3x - 2[/tex] ) (x + 3) =   [tex]2x^{3} +3x^{2} -11x - 6[/tex]
