Question

How can be here negative sign?
Division of polynomial by polynomial

Answer 1

Answer:

its wrong its positive sign not negative......

Answer 2

This is because when dividing one polynomial by another, we change the sign to the opposite(because we are subtracting). So to cancel out the minus sign with a polynomial with which starts with a minus sign, we use minus sign so that when we change the sign, the first term(which is negative here) gets cancelled.
