\[16a^2+40a+25 = (4a +5)(4a+5)= (4a+5)^2\]

@Kimberlina the method for this is calculate 25*16 = 400, now factorize the middle term so that sum of factors =40 and product of factors =400,i.e factors would be 20 and 20 , so you can write equations as \[16 a ^2 +20 a +20 a +25 = 4a (4a +5) + 5 (4a+5)\] =(4a+5)(4a+5) ...this method is also called middle term spilitting
