In question 77 for the option 1, how do you consider the eigen values are positive real ?

Hi Ma'am , please give me reason (in question no. 78) of writing that if xt(A-lamda I)x= O then (A-lamda I)= O. I find it wrong

[@mohdjaims8848]

Question is talking about existence of positive definite.

Ques 77 main kaisa pta chala lambda positive hai

Thanks ma'am ❤️

In Q75 if one eigen vale is real and two are complex for any real matrix then i think option (b) is wrong. A=[0 1 0 -1 0 0 0 0 1] It has eigen values are:1, i, -i So A is not diagonalizable over R ???

[@smaranikabiswal3439]

Option b. Say if A has distinct real eigenvalue then A is diagonizable But your eigenvalue is already complex then how is it diagonizable?
