Question

When you square each side of an equation, is the resulting equation equivalent to the original?

Answer 1

not quite
this process results in adding one more solution

for example,
x=2
(2 is the solution)

now square :
x^2 = 4
(-2,2 are the solutions)

Answer 2

(adding one more solution in the general case ofcurse)

if we had x=0
the square thing wont change anything

Answer 3

so is the answer yes?

Answer 4

since it doesnt change?

Answer 5

but i just showed you that it changes!

Answer 6

to x=2
we get
x^2=4
and we got another solution which is not the solution to the original one
