If `alpha `is a roots equations `4x^2+2x-1=0andf(x)=4x^3-3x+1,then2(f(alpha)+alpha)` is

If alpha is a roots equations 4x^(2)+2x-1=0 and f(x)=4x^(3)-3x+1, then 2(f(alpha)+alpha)

If alpha is a root of the equation 4x^(2)+2x-1=0 and f(x)=4x^(2)-3x+1 , then 2(f(alpha)+(alpha)) is equal to

If alpha is a root of the equation 4x^(2)+2x-1=0, then prove that 4 alpha^(3)-3 alpha is the other root.

If alpha be a root of the equation, 4 x^2 + 2x - 1 =0 , then 4 alpha^3 - 3 alpha is other root.

If alpha be a root of the equation,4x^(2)+2x-1=0, then 4 alpha^(3)-3 alpha is other root.

If -1,2,alpha are the roots of the equation 2x^(3)+x^(2)-7x-6=0, then alpha is

If alpha is a root of x^(4) + x^(2) - 1 = 0 , the value of (alpha^(6) + 2 alpha^(4))^(2012) is

If f(x)=4x^(2)+3x-7 and alpha is a common root of the equation x^(2)-3x+2=0 and x^(2)+2x-3=0 then the value of f(alpha) is

If alpha is a root of the equation 4x^(2)+2x-1=0 then the other root is given by O -2 alpha-1 O 4 alpha^(2)+alpha-1 O 4 alpha^(3)-3 alpha O 4 alpha^(2)-3 alpha
