Question

which of the following is a polynomial in one variable (i) 3 root x + root 2 x (ii) root 2 x^2+ root 3 (iii)x^2+x+y (iv) x- 4/x​

Answer 1

Answer:

Since, the given expression has only one variable 'x', hence this is a polynomial in one variable. Since, the given expression has only one variable 'y', hence this is a polynomial in one variable. Since, variable, 't' in this expression exponent of variable is not a whole number.
