**For each quadratic function**

a) State the matrix of the quadratic form associated with the given equation.  
b) Determine the eigenvalues of the matrix.  
c) Construct an orthogonal matrix \( P \) with \( |P| = 1 \) that diagonalizes your matrix from a).  
d) Write the equation of the function in the new coordinate system.  
e) Identify the type of conic or quadric surface described by the equation.  
f) Calculate the angle of rotation in degrees.  

1. Let \( p = 5 \). Let \( q = 8 \).  

   \( 5x^2 + 8xy + 5y^2 - p\sqrt{2}\,x + q\sqrt{2}\,y - 18 = 0 \)
