Question

Express -7 as a polynomial of degree zero.​

Answer 1

A polynomial of degree zero reduces to a single term A (nonzero constant). Examples: xyz + x + y + z is a polynomial of degree three; 2x + y − z + 1 is a polynomial of degree one (a linear polynomial); and 5x2 − 2x2 − 3x2 has no degree since it is a zero polynomial. ... Let P = P(x) and Q = Q(x), Q ≠ 0, be two polynomials.

Answer 2

No degree is assigned to a zero polynomial. A polynomial of degree zero reduces to a single term A (nonzero constant). Examples: xyz + x + y + z is a polynomial of degree three; 2x + y - z + 1 is a polynomial of degree one (a linear polynomial); and 5x² - 2x² - 3x² has no degree since it is a zero polynomial.
