A differential equation and a solution are given below. Find a second linearly independent solution using reduction of order. (1−2t−t2)x′′+2(t+1)x′−2x=0;t>0;x 1(t)=t+1(1−2t−t2)x″+2(t+1)x′−2x=0;t >0;x1(t)=t+1

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18
