1. Find the general equation. When the operator D is used it is implied that the independent variable is x. a. (D2 - 4D + 7)y = 0 b. (D2 - 22D + 121)y = 0 c. (D2 + 6D + 13)y = 0 d. (D2 + 16D + 64)y = 0 e. (D2 - 2D + 5)y = 0 f. (D2 - 8D + 16)y = 0 g. (D2 - 16)y = 0 h. (D2 + 10D + 25)y = 0 i. (D2 + 16)y = 0 j. (D2 - 14D + 49)y = 0
