If `A=[alpha2 2alpha]a n d|A^3|=125` , then the value of `alpha` is a.`+-1` b. `+-2` c. `+-3` d. `+-5`

If A=[(alpha , 2),(2,alpha)] and |A^3|=125 , then the value of alpha is :

if A=[{:(alpha,2),(2, alpha):}] and |A^(3)|=125 then the value of alpha is

If A = [{:( alpha , 2),( 2,alpha ) :}] and |A^(3) | = 125 then the value of alpha is

If A=[(alpha,2),(2,alpha)] and determinant (A^3)=125, then the value of alpha is (a) +-1 (b) +-2 (c) +-3 (d) +-5

If the ratio of the roots of the equation,x^(2)+alpha x+alpha+2=0 is equal to 2, then the value of alpha is: 3/2 b.-3/2 c.-6 d.6

If alpha^(2)=5 alpha-3 beta^(2)=5 beta-3 then the value of (alpha)/(beta)+(beta)/(alpha) is

If the ratio of the roots of the equation,x^(2)+alpha x+alpha+2=0 is equal to 2, then the value of alpha is: (3)/(2)(b)-(3)/(2)(c)-6 (d) 6
