SOLUTION: (1/9 h^6 + 6/7 h^2) + (3/4 h^6-1/28h^2) Ive done the problem and got 11h^6/18 + 23h^2/28 but it was wrong

Question 829589: (1/9 h^6 + 6/7 h^2) + (3/4 h^6-1/28h^2)
Ive done the problem and got 11h^6/18 + 23h^2/28 but it was wrong
Answer by LinnW(1048) (Show Source): You can put this solution on YOUR website!
(1/9 h^6 + 6/7 h^2) + (3/4 h^6-1/28h^2)
(1/9 + 3/4)h^6 +(6/7 -1/28)h^2
Use 36 as a common denominator for the h^6 coefficient
(4/36 + 27/36)h^6 + (6/7 -1/28)h^2
No use 28 as the common denominator for the h^2 coefficient
(4/36 + 27/36)h^6 + (24/28 -1/28)h^2

One could factor out h^2 to get
