Multiply. Give your answer in standard form. (3n2 + 2n + 4) (2n - 1) A. 6n3 + n2 + 6n - 4 B. 6n3 + 7n2 + 6n - 4 C. 6n3 - n2 + 10n - 4 D. 6n3 + n2 + 10n - 4

A

Step-by-step explanation:

(3n²+2n+4) (2n-1)

to solve this multiply through by using each term in one bracket to multiply all terms in the second bracket to open the bracket.

3n² (2n-1) + 2n (2n-1) + 4 (2n-1)

6n³-3n² + 4n²-2n+8n-4

6n³+n²+6n-4

Hence the correct option is A
