Question

please answer these guys in hurry​

Answer 1

Answer:

(xiv) c

(xiii)a

Step-by-step explanation:

(xiv) All the exponents in the algebraic expression must be non-negative integers in order for the algebraic expression to be a polynomial.

for (1/(x+1))= (x+1)^-1

so it is not a polynomial

(xiii) for a polynomial Ax^2+Bx+C,if the roots are a,b

then a+b = -B/A

and ab = C/A

so for the problem= 1/4
