If `|(x,2,3),(4,5,2),(5,2,3)|=0` then `x=`

If |{:(x, 2, 3),(2,3,x),(3 , x,2):}| = |{:(1, x, 4),(x,4,1),(4 , 1,x):}| = |{:(0, 5, x),(5,x,0),(x, 0,5):}| = 0, then the value x equals (x in R )

The roots of the equations |{:(1+x,3,5),(2,2+x,5),(2,3,x+4):}| = 0 are

A={:[(-5,-3,4),(3,2,-4)]:}andB={:[(-4,5,-2),(3,1,5)]:} , then find X such that 3A-2B+X=0.

If the [[x, 2,32,3, x3, x, 2]] = the [[1, x, 4x, 4,14,1, x]] = the [[0,5, x5, x, 0x, 0.5]] = 0

Let the equation x^(5) + x^(3) + x^(2) + 2 = 0 has roots x_(1), x_(2), x_(3), x_(4) and x_(5), then find the value of (x_(2)^(2) - 1)(x_(3)^(2) - 1)(x_(4)^(2) - 1)(x_(5)^(2) - 1).
