0=x*(xa-(-1b))-(-1*c) I am using det(a)=A11(A22*A33-A23*A32)-A12(A21*A33-A23*A31)+A13(A21*A32-A22*A31) Yes it is equal to zero sorry, new here. Ax^2+bx+c=0 so I am assuming my answer would be x = [-b ± √(b^2 - 4ac) ]/2a

Homework Statement | x 0 c| | -1 x b| = 0 | 0 -1 a| Homework Equations The Attempt at a Solution As best as I can tell I would end up with x * (xa - (-1b)) and -1c and then I would end up with Ax^2 + BX + C which leaves me confused am I looking at a quadratic...
