Is the difference of two polynomials always a polynomial? Explain.
Weegy: Let's try an example: The difference between (6x3 + x2 - 4x + 9) and (6x3 + x2 - 4x + 7) is 2 . 2 is a polynomial of degree 0, so this example would appear to support the hypothesis in the question. [ However, polynomials cannot include negative exponents. So, (2x)/(2x2) produces 1/x, which is not a polynomial. So no, not always. e_difference_of_two_polynomials_always_a_polynomial#ixzz21IDsiwzy ] User: Is the difference of two polynomials always a polynomial? Explain. (More)
