|A| shows determinant of matrix A.
So,
=> -2x- 5= -9
=> -2x = -4
=> x = 2
So, the answer is {2}

1.4. Solve the differential equation tx"– 2x' =0, x(1) = 7, x'(1)=6.
(1 point) In this problem you will solve the differential equation (+7)y"+11xy' - y=0. x" for the differential equation will converge at least on the interval (-inf.-sqrt(7)] (1) Ey analyzing the singular paints of the differential equation, we know that a series solution of the form y = . (2) Substituting y = . *" into (x2+7y" + 11xy - y = 0, you get that Multiplying the coefficients in x through the sums E Reindex the sums Finally combine...
