What is the product of the binomials (4a - 1) and (2b + 3) ?

A=18ab - 3

B=8a2b2 + 10ab - 3

C=6ab + 7a - 2b - 3

D=8ab + 12a - 2b - 3

Multiplying binomials can be done by distributing the first term of binomial 1 to the second binomial and then adding it to the product of the distribution of the second term of binomial 1 to the second binomial. This is shown below:

(4a - 1) (2b + 3) = 8ab + 12a - 2b - 3

From the choices, the correct answer is D.
