Hi - I hoped someone maybe able to help me understand this question:
(apologies but I can't find the syntax for absolute value sign)
I know that I would need to square both sides in order to remove the modulus. But when rearranging I dont end up with a product so unsure how to proceed.
So with what you say in mind. If I draw a number line x cannot be equal to 5 or 3 but can be -1. And it will be always be positive between critical values because of the squaring of each parenthesis. Therefore the answers will be:
Is this correct?
