If `|[2x,-4],[3,x]|=|[x,-6],[3,-1]|` then `x` is

Solve for x: /_\=|[2x,3,1],[4,6,x],[3x,1,1]| = 0

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 f(x)=|[3,2,1],[6x^(2),2x^(3),x^(4)],[1,a,a^(2)]| ,then f''(a)= is

If (3x+1)^3+(x-3)^3+ (2x-4)^3= 6(3x+1)(x - 3)(x -2) then what is the value of x? / यदि (3x+1)^3+(x-3)^3+ (2x-4)^3= 6(3x+1)(x - 3)(x -2) है, तो x का मान क्या होगा ?

|[x^2+3,x-1,x+3],[x+1,-2x,x-4],[x-3,x+4,3x]|=px^4+Qx^3+rx^2+sx+t

Let F(x)=|[1,1+sin x,1+sin x+cos x],[2,3+2sin x,4+3sin x+2cos x],[3,6+3sin x,10+6sin x+3cos x]| then the value of F'((pi)/(2)) =

4+x^(2),-6,-2-6,9+x^(2),3-2,3,1+x^(2)]| is

If mean of x,2x+1,2x-1 is 10, then value of x is 2 4 6 3
