when a mod is removed from expression, do the (+,-) signs go over other side or they are applied on the same side/expression which had mod over it? Are the signs in the image opened correctly?

It doesn't matter on which side you put them. If they are on the left side you can multiply both sides by -1 after which they will be on the right side

so could it had been +-(x^2+x) = x+2?

#

yes that would also work

#

notice that if you choose + you get the first equation and if you choose - and multiply both sides by -1 you get the second equation

is opening mod from one side and putting signs on the other side has any exception?

this always works. If you have a mod on one side and you want to remove it you can always choose on which side to put the +-.

#

But after all it doesnt make a big difference. In the end you will have to solve two equations no matter on which side you put the +- and the only difference between these equations is that one of them is multiplied by -1.

so both the ways are correct without exceptions?

ruby wasp Jun 2, 2025, 10:42 AM

Yes
