then if f and g satisfying the matrix equation A^2 + fA + gl = 0,с
then values of fand g are respectively.
(1) f--a+d).g-ad-bo
(3) f - (a-d).g-ad - be
(2) f = (a + d).g-ad- be
(4) f = (a -d). g - ad + bc​

Answer 1

Answer:

50. If A-

then if f and g satisfying the matrix equation A^2 + fA + gl = 0,с

then values of fand g are respectively.

(1) f--a+d).g-ad-bo

(3) f - (a-d).g-ad - be

(2) f = (a + d).g-ad- be

(4) f = (a -d). g - ad + bc
