If the equation `x^2-b x+1=0` does not possess real roots, then `-32` (d) `b<-2`

If the equation x^2-b x+1=0 does not possess real roots, then -3 2 (d) b<-2

If the equation x^2-b x+1=0 does not possess real roots, then range of b

If the equation x^(2)- bx+ 1 = 0 does not possess real roots, then which one of the following is correct?

If the equation a x^2+b x+c=x has no real roots, then the equation a(a x^2+b x+c)^2+b(a x^2+b x+c)+c=x will have a. four real roots b. no real root c. at least two least roots d. none of these

If the equation a x^2+b x+c=x has no real roots, then the equation a(a x^2+b x+c)^2+b(a x^2+b x+c)+c=x will have a. four real roots b. no real root c. at least two least roots d. none of these

If the equation a x^2+b x+c=x has no real roots, then the equation a(a x^2+b x+c)^2+b(a x^2+b x+c)+c=x will have a. four real roots b. no real root c. at least two least roots d. none of these

If the equations x^(2) + ax+1=0 and x^(2)-x-a=0 have a real common root b, then the value of b is equal to

Show that the equation 2(a^(2)+b^(2))x^(2)+2(a+b)x+1=0 has no real roots when a!=b .

Show that the equation 2(a^(2)+b^(2))x^(2)+2(a+b)x+1=0 has no real roots,when a!=b

If one root of the equation (a-b) x^(2)+a x+1=0 is double the other and if a is real, then the greatest value of b is
