" Q."79" If "x" is a non-real root of the equation "x^(6)-1" then "(a^(2)+a^(3)+a^(4)+a^(5))/(a+1)=

If alpha is a non real root of the equation x^(6)-1=0 then (alpha^(2)+alpha^(3)+alpha^(4)+alpha^(5))/(alpha+1)

Real roots of the equation x^(2)+6|x|+5=0 are

Sum of the real roots of the equation x^(2)+5|x|+6=0

Find the real roots of the equation . x^2+5|x|+6=0

If alpha is a non-real root of x^(6)=1 then (alpha^(5)+alpha^(3)+alpha+1)/(alpha^(2)+1)=

If alpha is a non-real root of x^(6)-1=0 then (alpha^(5)+alpha^(3)+alpha+1)/(alpha^(2)+1)

No of non real real roots of the equation x^(10)-3x^(8)+5x^(6)-5x^(4)+3x^(2)-1=0

The real roots of the equation 5^("log"5(x^(2) - 4x + 5)) = x - 1 are :

The number of real roots of the equation x^5+e^(8x)=0 is (1)0 (2) 1 (3) 2 (4) 3
