What's the answer for x^2-2x+3 and 2x^2+9x+4?
Writing an algebraic expression like a polynomial does not constitute asking a question.
Are they supposed to be equations you are trying to solve? If so, you need to say what they are equal to.
Are you trying to "factor" them?
The second polynomial factors into
(2x+1)(x+4). The first cannot be factored without using complex numbers. Did you mean to write x^2 -3x + 2?
THAT can be factored
