Which is a correct expansion of (2x + 3) (2x2 - 5) ?

A. 2x• 2x2 + 3 • 2x2 + 2x2: (-5) + 3 • (-5)

B. 2x• 2x2 + 2x• (-5) + 3 • 2x2 + 3 • (-5)

C. 2x• 2x2 + 2x: (-5) + 3 • 2x+3 • (-5)

B. 2x• 2x2 + 2x• (-5) + 3 • 2x2 + 3 • (-5).

Step-by-step explanation:

(2x + 3) (2x2 - 5)

First multiply the second parentheses by 2x then by + 3:

= 2x (2x2 - 5) + 3 (2x^2 - 5)

= 2x• 2x2 + 2x• (-5) + 3 • 2x2 + 3 • (-5).
