Two quadratic trinomials and a sort of kluge quadratic binomial (though I suspect at typo in the third expression).
So exactly what part of "One problem per post" don't you understand?
What part of "ask your question clearly and fully so that it MAKES SENSE. We are not mind readers. We do not have your textbook in front of us. All we know is what you wrote," don't you understand?
What part of "in order to be successful in school, you actually have to do some work of your own" don't you understand?
