There are two numbers x making the value of the determinant` |[1,-2,5],[2,x,-1],[0,4,2x]|` equal to 86. The sum of these two numbers is-

There are two values of a which makes determinant , A=|(1,-2,5),(2,a,-1),(0,4,2a)|=86 , then sum of these numbers is :

There are two values of 'a' which makes the value of determinant |(1,-2,5),(2,a,-1),(0,4,2a)| = 86 , find the sum of these values of 'a'.

If there are two values of a which makes determinant, Delta=|(1,-2,5),(2,a,-1),(0,4,2a)|=86 then the sum of these number is

If there are two values of a which makes determinant, Delta=|(1,-2,5),(2,a,-1),(0,4,2a)|=86 then the sum of these number is

If there are two values of a which makes determinant, Delta=|(1,-2,5),(2,a,-1),(0,4,2a)|=86 then the sum of these number is

There are two values of a which makes determinant Delta=|{:(1,-2,5),(2,a,-1),(0,4,2a):}|=86 , then sum of these number is "........."

If 1, log_(10)(4^(x)-2) and log_(10)(4^(x)+(18)/(5)) are in arithmetic progression for a real number x, then the value of the determinant |(2(x-(1)/(2)), x-1,x^(2)),(1,0,x),(x,1,0)| is equal to:

Find the value of x if |(1,4,20),(1,-2,-5),(1,2x,5x^2)|=0
