just add the negative of the polynomial, that is the same as subtracting it. For example, x^2+2x is a poly, the negative is -x^2-2x. So if we want to subtract x^2+2x from another poly, we can add the negative instead.
You subtract a polynomial by adding its additive inverse. For example, subtracting (x - y) is the same as adding (-x + y). Alternately, you can simply subtract similar terms - that is, subtract the coefficients (the numbers) for terms that have the same combination of variables.
