you like‚ just consider this step as‚ “subtract from each diagonal element of the matrix in the question”. Next we derive a formula for the determinant‚ which must equal zero: We now need to find the roots of this quadratic equation in . In this case the quadratic factorises straightforwardly to: The solutions to this equation are and . These are the eigenvalues of

performance of Authorised Deposit-taking Institutions (ADIs) using explicitly Australian data? This paper investigates the relationship between capital structure and firm performance of Australian ADIs. Our findings show a significant and robust quadratic relationship between capital structure and firm performance of Australian ADIs. At relatively low levels of leverage an increase in debt leads to increased profit efficiency hence superior bank performance‚ at relatively high levels of leverage increased

the 0 a) M-3=0 Step 3. 2m+5=0 Divide each term in A by “2” Solve: a) m=-5/2 For the second problem the quadratic formula will be used to solve the equation. Since a=2y^2 b=3y c=6 and we know these are integers and two terms complete the square‚ we can also see in our equation we have the discriminant so we determine if we have a prime polynomial. Using the quadratic formula: Original equation: 2y^2-3y-6=0 Step 1: y=-b± b^2-4ac/(2a) so we will have our equation of ay^2+by+c=c
