Hello, let's note A the matrix, we need to find
such that A
=
I, where I is the identity matrix, so the determinant is 0, giving us the characteristic equation as

We just need to solve this equation using the discriminant.

And then the eigenvalues are.

To find the basis, we have to solve the system of equations.

Answer:
g = 10.82
_______ or 5.694736842105263
-1.9
Step-by-step explanation:
- 1.6g - 0.3g = 6.46 + 4.36
-1.9g = 10.82
g = 10.82
_____
-1.9
you find what they both divide by and then divide each one and then you keep doing that until you cant no more
