... dt2 dt The associated auxiliary equation is r2 + 6r − 7 = 0, which has two roots r1 = 1, r2 = −7. Then {ex , e−7x } is a fundamental solution set, and a general solution is y(t) = c1 et + c2 e−7t = c1 et + c2 (et )−7 . Expressing y in terms of the original variable x, we find y(x) = c1 x + c2 x−7 . ...
