Hey there!

\bold{x^2+5=21}x

2

+5=21

Firstly, subtract by the number \bold{5}5 on each of your sides

\bold{x^2+5-5=21-5}x

2

+5−5=21−5

\bold{Cancel:5-5}Cancel:5−5 because it gives us the result of \bold{1}1

\bold{Keep:21-5}Keep:21−5 because it equals: \bold{16}16

\bold{x^2=16}x

2

=16

Nextly, we have to take our square root

\bold{x=}x= ±\bold{\sqrt{16}}

16

Solve the square root and you have found your answer

\boxed{\boxed{\bold{Answer:x=4[or]x=-4}}}

Answer:x=4[or]x=−4

\bold{\checkmark}✓

Good luck on your assignment and enjoy your day!
