Hello, please break down step by step. Thank you.

Consider the recurrence T(n)=2T(n/4)+n2 (a) Use the recursion tree method to get a tight upper bound (i.e. big-0) on the solution to this recurrence. (b) Use annihilators (and a transformation) to get a tight upper bound on the solution to this recurrence. 5 Show your work. Note, your two bounds should match
