Please solve for both cases a > b and a

(Problem 3 continued) D. [12 pts] Suppose that a and b are unspecified real numbers. Calculate 1 x2 + ax + 6 dx. Hint: Make sure to reflect carefully on Part C when you decide what needs to be done to perform the integration. I, your technique depends on a relationship between a and b, make sure to state what that relationship is. dx x ' tax + b 4: 2x +9 du : 276 - a b - 4 dx ( x+ 9/ 2 )"+ 6-4 dx = 1b - at Vb - 9/ 4 0 up + 1 : 20 + in (46- 92) us 4 + b 4 : a arctane du b 4 2 A = Q2 - Hb = o 02 = 410
