First lets simplify the first term and yield (2a)

The second term:
1.   2a * (-1/2) = -a
2.   -a + a = 0

Now we have simplified both terms to: (2a) (0)

Anything multiplied by 0 is 0, so the answer is also 0. 
Billymkhoi
a(2)*(2a(-1/2)+a)
= (2a)*(-1*a+a)
=(2a)*(-a+a)
=(2a)*0
=0

So 0 is the final answer.

Hope this would help :))
