Hey there!
- [tex]\bold{x^2+5=21}[/tex]
- Firstly, subtract by the number [tex]\bold{5}[/tex] on each of your sides
- [tex]\bold{x^2+5-5=21-5}[/tex]
- [tex]\bold{Cancel:5-5}[/tex] because it gives us the result of [tex]\bold{1}[/tex]
- [tex]\bold{Keep:21-5}[/tex] because it equals: [tex]\bold{16}[/tex]
- [tex]\bold{x^2=16}[/tex]
- Nextly, we have to take our square root
- [tex]\bold{x=}[/tex]±[tex]\bold{\sqrt{16}}[/tex]
- Solve the square root and you have found your answer
- [tex]\boxed{\boxed{\bold{Answer:x=4[or]x=-4}}}[/tex] [tex]\bold{\checkmark}[/tex]
Good luck on your assignment and enjoy your day!
