Question

xsqare +1 has no zeroes why
​

Answer 1

Answer:

$\sf \red{Answer \: and \: Explanation:}$

Given: Expression $\sf \pink{x² + 1}$ has no real zeros.

To find : Why?

Solution :

First we solve the expression and find the zeros,

$\bf \red{x^2+1=0}$

Subtract 1 both side,

$\sf \purple{x^2=-1}$

Taking root both side,

$\bf \red{\sqrt{x^2}=\sqrt{-1}} \\ \bf \purple{x=\pm i}$

Here, i is the imaginary term.

Here, i is the imaginary term.So, The expression has no real zeros.
