Answer:

2 x^2 + -5 x - 3

Step-by-step explanation:

Expand the following:

(x - 3) (2 x + 1)

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

2 x x + x - 3 2 x - 3

x×2 x = 2 x^2:

2 x^2 + x - 3 2 x - 3

-3×2 = -6:

2 x^2 + x + -6 x - 3

x - 6 x = -5 x:

Answer:  2 x^2 + -5 x - 3
