Answer:

[tex]x=5,x=-5[/tex]

Step-by-step explanation:

[tex]x^2-25=0[/tex]

Add 25 to both sides:

[tex]x^2-25+25=0+25[/tex]

[tex]x^2=25[/tex]

Square root both sides:

[tex]x=\sqrt{25},\:x=-\sqrt{25}[/tex] (Since a negative number multiplied by itself gives positive, there are two answers.)

[tex]x=5,x=-5[/tex]

Hey there!

ANSWER: [tex]x=5\\x=25[/tex]

EXPLANATION:

[tex]x^2-25=0[/tex]

The first step we have to do is to add 25 to both sides of the equation.

[tex]x^2-25+25=0+25\\\text {equals }x^2=25[/tex]

In our last and final step, we will have to take the square root.

[tex]x=[/tex] ±[tex]\sqrt{25}[/tex]

We have two answers.

[tex]x=5(ANSWER)\\x=-5(ANSWER)[/tex]

Hope this helps!
