why can’t we simplify 3x2+4x any further. If you were to incorrectly simplify this expression into a single term, what would that single term look like? Now, pick 1 or 2 numbers to plug in for “x” in 3x2+4x and your incorrectly-simplified single term expression. Compare the numbers you get. What conclusions can you draw?
You cannot combine an x2 and an x term.
You could "incorrectly" simplify it to anything. This is a nutty question: similar to asking what is the correct wrong answer to 4+7. Nuts to this question.
