Answer by ehollins1(8)   (Show Source):
You can put this solution on YOUR website! =9a^2+24a+16 possible factors for a^2: 1,a,a^2
=(a+)(a+) possible factors for 9: 1,3,9
=(3a+ )(3a+ ) possible factors for 24: 1,2,3,4,6,8,12,24 possible factors for 16: 1,2,4,8,16 LCM: 4
=(3a+4)(3a+4)
solution:(3a+4)(3a+4)
*****check solution*****
=(3a+4)(3a+4)
=(3a*3a)+(3a*4)+(4*3a)+(4*4)
=9a^2+12a+12a+16
=9a^2+24a+16
