Question

solve sq. y-13 + sq.y =13

Answer 1

First get 1 sqrt thingy by itself then square both sides so you can get rid of that sqrt but you will still have another sqrt on the other side so you get that one by itself and then square again

Answer 2

no more sqrt thingy

Answer 3

so we have (y-13)^(1/2)=13-y^1/2

Answer 4

square both sides

Answer 5

y-13=(13-y^(1/2))^2

Answer 6

sorry to interrupt.
@myinaya, like the way you said "sqrt thingy" XD

Answer 7

lol

Answer 8

i just thought it is easier to understand

Answer 9

y-13=169-2y^1/2+y

Answer 10

remember get that last sqrt thingy by itself

Answer 11

y-y-13-169=2y^(1/2)

Answer 12

oh mine thought we ran into some like terms. Lets just combine them real quick

Answer 13

though*

Answer 14

-199=2y^(1/2)

Answer 15

so we have -199/2=y^(1/2) then square both sides (-199/2)^2=y

Answer 16

You should always check your solutions when you raise both sides to an even power though

Answer 17

so y= -199/2^2

Answer 18

y = (-199/2)^2

Answer 19

and actually it was suppose to be (199/2)^2 but it doesnt matter since it is squared

Answer 20

this is so confusing to me ....haven't been in school for 20+ years

Answer 21

like i forgot to write a negative sign before the last step
