If |(1,-3,4),(-5,x+2,2),(4,1,x-6)|=0 then x equals

Evalute the determinants in queations 1 and 2 : Find the values of x, if (i) |{:(2,4),(5,1):}|=|{:(2x,4),(6,x):}| (ii) |{:(2,3),(4,5):}|=|{:(x,3),(2x,5):}|

If f(x)=|[3x^2-x+3,6x-1,4],[6x^2-4x+5,12x-4,8],[3x^2+2x+5,6x+2,4]|, then the degree of the polynomial f(x) is

If the trace of the matrix A= [{:( x-1 ,0,2,5),( 3, x^(2) - 2 ,4,1),( -1,-2,x-3,1),(2,0,4,x^(2)-6) :}] is 0 then x is equal to
