Answer: 12a2+48a+48

Step-by-step explanation:

(6a+12)/5.10(a+2)

. dot in mathematics means ×

So we can say

((6a+12)/5)×10(a+2)

((6a+12)/5)×10(a+2)/1

The 5 can be used to divide d 10

So we have

(6a+12)×2(a+2)

Open the bracket

(6a+12)×(2a+4)

(6a+12)(2a+4)

Open the bracket

12a2+24a+24a+48

12a2+48a+48
