Answer:

B. 1,3

Step-by-step explanation:

Formula

Replace the blanks by 1 and 3 respectively

(4x + 1 ) ( x + 3 )

solve:

(4x + 1 ) (x + 3)

multiply 4x by x = 4x²

multiply 4x by 3 = 12x²

multiply 1 by x = 1x or just x

multiply 1 by 3

=4x² + 12x + 1x + 3

add 12x and 1x = 13x

= 4x² + 13x + 3
