Question

12) Which of the following expressions is polynomial in 1 variable? * a]y + 1/y, b]√x + 4, c]2t² + 5, d]x² + x + 1/x fast answer it

Answer 1

Therefore, x = -1/3 is a zero of polynomial p(x) = 3x + 1. (ii) If x = 4/5 is a zero of polynomial p(x) = 5x – π then p(4/5) should be 0. At, p(4/5) = 5(4/5) – π = 4 – π. Therefore, x = 4/5 is not a zero of given polynomial p(x) = 5x – π. (iii) If x = 1 and x = -1 are zeroes of polynomial p(x) = x² – 1, then p(1) and p(-1)

hope it helps

Answer 2

Answer:

(i) and (ii) are polynomials is one-variable (iii) is not polynomial (iv) is not a polynomial (v) is a polynomial in three variables.
