In Problems 15-30 use the procedures developed in this chapter to find the general solution of each differential equation.
15. y" 2y 2y = 0
16. 2y" + 2y' + 3y = 0
17. y" + 10y" + 25y' = 0
18. 2y" +9y" + 12y' + 5y = 0
19. 3y"" +10y" + 15y' + 4y = 0
20. 2y(4) + 3y" + 2y" + 6y' - 4y = 0
21. y" - 3y + 5y = 4x³ - 2x 22. y" - 2y' + y = x²ex n part. Due to electronic rights, some third party content may be suppressed from the eBook and or eChapter(s). Editorial
