Question

Show that x2-4x+9 have no zeros

Answer 1

x²-4x+9=0

x²= -9+4x

there is no zero

Answer 2

Answer:

It will have roots but imaginary.

It will not have real roots or zeroes.

Step-by-step explanation:

The given equation is x^2-4x+9. Here a=1 , b=-4, C=9.

Now it's discriminant (D)

D=b^2-4ac

putting the values of a,b,c we get,

D=(4)^2 - 4*1*9

=16 - 36

=-20

Here D is less than 0. So, the equation x^2-4x+9 will have no zeroes.
