Answer:
x=[tex]\sqrt{5}[/tex]
Step-by-step explanation:
f(x)=[tex]x^{2}[/tex]-5
[tex]x^{2}[/tex]-5=0
Add 5 to both sides.
[tex]x^{2}[/tex]=5
To get rid of the square of x, put the square root thingie so that it will cancel out. BTW, if you put it on one side, you have to put it on the other side.
[tex]\sqrt{x^{2} }[/tex]=[tex]\sqrt{5}[/tex]
x=[tex]\sqrt{5}[/tex]
Hope this helps! Plz give brainliest!
