Question

how do you solve equations like this?
2x^2=32

Answer 1

hint:

divide both sides by 2 to get

2x^2=32

2x^2/2=32/2

1x^2 = 16

x^2 = 16

x = ??? or x = ???

Answer 2

^^^^ what you have is good so far, now just take the square root of x^2 and 16 so that it just becomes: x = 4

Answer 3

ohhhhh okay omg thank you!

Answer 4

can we try another one real quick and see if i got this down?

Answer 5

remember that if x^2 = 16, then x = 4 or x = -4

Answer 6

there are two solutions here

Answer 7

this is because 4^2 = 16 and (-4)^2 = 16
