Question

X square+1 has no real zeros why

Answer 1

Hey!

x² + 1

$x {}^{2} + 1 = 0$

$x {}^{2} = - 1$

$x = \sqrt{ - 1}$

x = i
is not a real number.

So, x² + 1 have no real roots!

Hope helped.

Answer 2

Answer and Explanation:

Given : Expression $x^2+1$ has no real zeros.

To find : Why?

Solution :

First we solve the expression and find the zeros,

$x^2+1=0$

Subtract 1 both side,

$x^2=-1$

Taking root both side,

$\sqrt{x^2}=\sqrt{-1}$

$x=\pm i$

Here, i is the imaginary term.

So, The expression has no real zeros.
