# How do I explain the correct process used to simplify subtracting polynomials and put it in words

I am having issues with how to word out this whole thing, math is one of my most weakest link as a student especially when it comes to explaining a problem out. I need help simplifying (3x2 -4x +7) – (-5x2 +12x -9) and give your final answer in simplest form. How do I show that my solution is correct by evaluating it for m = -3 in the original expression and in your expression. And what would one situation would be a good example of a real life use of polynomials.
