Find the characteristic polynomial of a. use x for the variable in your polynomial. you do not need to factor your polynomial. a = [0 0 1] [ 4 -3 4] [-2 0 -3] 1. haracteristic polynomial of a is

 The required characteristic polynomial of the given matrix A is

Step-by-step explanation:  We are given to find the characteristic polynomial  of the following 3 × 3 matrix A  with unknown variable x :

We know that

for any square matrix M, the characteristic polynomial is given by

where I is an identity matrix of same order as M.

Therefore, the characteristic polynomial of matrix A is

Thus, the required characteristic polynomial of the given matrix A is

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
