<PRE><B>Question 164454</B>
Please check over I came up with (x+4)(9x+4) 
Factor completely:
9x^+40x+16

(x+4)(9x+4) let&#39;s use the FOIL (first, outer, inner, last) crutch to expand and we get:
9x^2+4x+36x+16=
9x^2+40x+16

LOOKS LIKE YOU NAILED THIS ONE!!!!!!!!!

Hope this helps---ptaylor
