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.

Thank you
If you are having trouble with ratios, turn them into fractions.
ex; 3 : 5 = 3/5, 8 : 10 = 8/10, 6 : 15 = 6/15
After you have turned all of your ratios into fractions, you can find a common denominator for all the fractions.
ex; 3/5, 8/10, 6/15 ⇒ 3/5, 4/5, 2/5
Now it you can easily order the ratios from least to greatest.
ex; 6 : 15, 3 : 5, 8 : 10
-(-2)^4 = 16
The - sign multiplies inside the bracket to a positive, 2^4 = 16
