Factor the following polynomial written in Standard Form. Select the correct answer from the choices listed below: 9d^2+12d+4
(3d + 4) (3d + 1)

(d + 2) (9d + 2)

(3d + 2) (3d + 2)

(9d + 1) (d + 4)

Respuesta :

C

(3d + 2) (3d + 2)

= 9d^2 +6d +6d +4

= 9d^2 +12d +4
The answer is (3d+2) (3d+2).
Steps:
Break the expression into groups:
(9d^2+6d)+(6d+4)
Factor out 3d from 9d^2+6d:
3d(3d+2)
Factor out 2 from 6d and 4: 2(3d+2)
=3d(3d+2)+2(3d+2)
Factor out common term (3d+2)
=(3d+2)(3d+2)

Hope this helps you! (:
