What is the factored form of the expression? 12d^2 + 4d – 1 A. (6d + 1)(2d + 1) B. (6d – 1)(2d – 1) C. (6d – 1)(2d + 1) D. (6d + 1)(2d – 1) A, B, C, or D? Please explain (:
As I said, start by checking the signs, it can't be +1*+1 or -1*-1 so it got to be C or D
Do you know the distributive laws?
Thanks for the help (:
