I assume you are asking for:      3 ( x² + 7 )

Just distribute them by multiplying 3 each to x² and 7
  
         =  3 (x²) + 3 (7)
         = 3x² + 21

To solve that use distributive property of multiplication simply as this. First, 3 times   is 3 plus 3  times seven is (equals) = 21. So, the answer is 3+21.  Do not forget that two is the exponent.
