Answer:
+-5
Step-by-step explanation:
[tex]x^{2}[/tex]=25
Square both sides to get...
x= [tex]\sqrt{25\\}[/tex]
To simplify it, we know that 5*5=25 so..
[tex]\sqrt{25}[/tex] = 5
And don't forget it can be -5 or 5
Step-by-step explanation:
x² = 25
power of square move to other sides become square root
x = √25
x = -5 or +5
