To simplify the expression 9•c^2/2+6+ (c^2/2+1) + c^2, we can combine like terms.
First, we can simplify the terms involving c^2:
9•c^2/2 + c^2/2 + c^2 = (9/2 + 1/2 + 1)•c^2 = 10•c^2
Next, we can combine the constant terms:
6 + 1 = 7
Putting it all together, the simplified expression is:
10•c^2 + 7
9•c2/2+6, c2/2+1, c2
