[0,x+2,x+6,x-1],[x+6,x-1,x+2," find "x],[x-1,x+2,x+6,]

|[x+2,x+6,x-1],[x+6,x-1,x+2],[x-1,x+2,x+6]|=

Using the properties of determinants, find the value of x, if: {:|(x+2,x+6,x-1),(x+6,x-1,x+2),(x-1,x+2,x+6)|=0

Solve the following equations.|(x+2,x+6,x-1),(x+6,x-1,x+2),(x-1,x+2,x+6)|=0

If x+1/x=6, find : x^2+\ 1//x^2

If x+(1)/(x)=6, find :x^(2)+1/x^(2)

If f(x)= [[x,x^2,x^3],[1,2x,3x^2],[0,2,6x]] find f'(x)

If x + (1)/(x) = 6 , then find x^(2) + (1)/(x^(2)) .
