Polynomial subtraction is carried out quite definitely the same manner as polynomial addition. Care must be taken about the negative sign, which appears between the two polynomials. Again if you’re good to collect the like terms in the polynomials, then polynomial subtraction is simple for you. As I already have mentioned that there’s the negative sign between the polynomial which becomes the main cause of the lot of problems. Once pupils understood this unfavorable sign, then the procedure is comparable to addition of polynomials. Consider there’s a trinomial, 12p – 9q + 6 and another polynomial with four conditions, – u + 5p + 8q – 15.
Let us subtract the polynomial with four conditions from the trinomial. Now collect the comparable terms same manner as we did for adding the polynomials. There is only one term containing variable u, which had no other similar term, thus it remains alone. Now, all the conditions are unlike in the final step, consequently quit there to leave that as answer. 7p – 17q + u + 21 is the final answer for subtraction of the given polynomials. There can be more complicated problems involving inclusion and subtraction of the polynomials. In such issues there are numerous variables to deal with or the polynomials concerned, have higher levels. In case the pupils know how to collect the comparable terms and know th whole rules well then any sort of polynomial addition or subtraction may be performed with the same ease.
