Although we often hear people say, ‘I would like to discuss about the problem’, it is not grammatically acceptable. You usually ‘discuss something’, you do not ‘discuss about’ something. The word ‘discuss’ is not followed by ‘about’.
Example, “we will not discuss what happened at the meeting.”
The word ‘discussion’, on the other hand, can be followed by ‘about’. Example: There will be no discussion about what happened at the meeting.
