Answer 3

k

Answer 4

do you know where to start?
try to divide both sides by 5
you get x^2 = 10
then take square root of both sides
you get x=+squareroot(10)
you also get x=-squareroot(10)

Answer 5

How did you get the negative? This means there's two answers? THANKS for the explanation it helps

Answer 6

:)

Answer 7

every time you take a square root, there are 2 answers, a positive answer and negative answer
example
x^2=4
x=+2 and -2
you can do (+2)^2 to get 4
you can also do (-2)^2 to get 4
be careful with parenthesis
-2^2 doesnt equal (-2)^2

Answer 8

That makes sense! Thanks :)
