Answer 1

@jim_thompson5910

Answer 2

y^2 - 250 = 0

y^2 = 250

I'll let you finish up

Answer 3

@jim_thompson5910 125?

Answer 4

no

Answer 5

you have to take the square root of both sides and simplify

Answer 6

don't forget about the plus/minus

Answer 7

do i do sq root of 2 and sq root of 250?

Answer 8

y = sqrt(250)

y = ???

Answer 9

62500

Answer 10

square root, not square

Answer 11

250^2 = 62500

but the square root, or sqrt, is the opposite

Answer 12

oh u divide?

Answer 13

no

Answer 14

square root

Answer 15

so 250 x 250?

Answer 16

no

Answer 17

idk how you're getting that

Answer 18

square root is not the same as squaring a number

Answer 19

i never knew that

Answer 20

so what do i do?

Answer 21

example

6 squared = 6^2 = 6*6 = 36

going in reverse

the square root of 36 = sqrt(36) = 6

Answer 22

see the difference?

Answer 23

so 250 x 2

Answer 24

no

Answer 25

y = sqrt(250)

how would you simplify that

Answer 26

250 x 250?

Answer 27

which number in the list below

1, 4, 9, 16, 25, 36, 49, 64, 81, 100

is a factor of 250 ?

Answer 28

25 @jim_thompson5910

Answer 29

good

Answer 30

so 250 = 25*10

Answer 31

which means

y = sqrt(250)

y = sqrt(25*10)

y = sqrt(25)*sqrt(10)

y = 5*sqrt(10)

Answer 32

so the two solutions are

y = 5*sqrt(10)

or

y = -5*sqrt(10)

Answer 33

don't forget about the plus/minus

Answer 34

how do u know which one to choose?

Answer 35

both are solutions

Answer 36

since both satisfy y^2 - 250 = 0

Answer 37

thanks!
